Von Schweikert
Research
Far from
sitting back and relaxing over the great success of his first two models, the
VR-4 and VR-3, Albert Von Schweikert has been burning
the midnight oil designing a whole slew of new models, both for stereo and home
theater. The VR-6 and VR-8, his two new reference speakers, take the fabulous
sound of the VR-4 to new heights. These two models differ only in the size of their
base cabinets and drivers. They share an incredible lucidity and spatiality and
are true benchmarks of high end accomplishment. The VR-8 recently received an
unmitigated rave review by none other than Harry Pearson, editor of The
Absolute Sound and father of the high end audio movement. For those of you not
familiar with Von Schweikert, all of their speakers
use a special circuit technology called the Global Axis Integration Network
(GAIN) system. GAIN launches the sound into your room with the same dispersion
pattern of the microphone that was used to record it. This puts a sound field
into your room which is a much closer replica of the original than can be
obtained with other speakers. The result is a hauntingly believable
presentation which allows the walls to fall away and lets you enjoy the image
as it existed in the concert hall. There has also been a redesign of the VR-4,
resulting in the new VR-4 Gen II. It's trimmer looking than its predecessor,
and some aspects of the internal cabinetry have been improved. An excerpt from
the July, 1998, rave review of this speaker which appeared in Sound Stage magazine
is shown below.
Music
through them transcends the mechanism of reproduction, allowing the listener to
hear past the medium and back to the true message of the music. They function
as time machines, providing the most direct path back to the musical event I've
ever had in my listening room. Such crystalline clarity, vivid detail,
articulate and extended bass, equality of balance, realism of presentation and
emotional involvement have never been more successfully integrated into one
more attractive and affordable package in my near 30 years of searching. The
VR-4 Generation II may well be the first true landmark or milestone product
I've had the pleasure of reviewing over the last decade. This speakers ability to completely get out of its own way and
resurrect only the recorded performance is unrivaled in this extremely
competitive price range, finally bringing previously unbelievable levels of
performance below the $4000 mark. It, in fact, bests some well-known entrants
from some very respected manufacturers selling for
nearly twice as much. I still find it next to impossible to give over to the
music and do anything else when my system is playing with the alluring Von Schweikert VR-4 Generation IIs. From me, there is no higher
recommendation.--Greg Weaver, Sound Stage, July, 1998
Then there are the many new models designed especially for home theater.
There are three new center channels, three new surround models, two new fronts,
and a subwoofer. These are true, high end home theater products. They tackle
the demands of reproducing soundtracks by being accurate, not by exaggerating
parts of the audio spectrum for special effects. These speakers are equally
comfortable reproducing music and soundtracks because they are neutral. This is
a great way to build a home theater/music system.
The System
Von Schweikert VR-8 speakers with the silver internal wire
option were used throughout. These extremely revealing speakers were set up in
a large room and placed about 6 feet from one side wall and more than 15 feet
from the other. Only 26 inches from the front wall proved the best bass
compromise in an irregular California style split level living area of greater
than 25,000 cubic feet. The back wall was not parallel, with the furthest point
about 45 feet away. The floor has a moderately thick carpet and the ceiling is
open wood-beamed cathedral, angling up and away from the speaker position. The
speakers sound good in this location without room treatment, almost a necessity
due to Wife Acceptance Factor (WAF) (not to say that the usual tricks wouldn’t
improve things). The speakers were separated by about 12 feet center to center
and the listening position was about 11 feet from the speaker centerline. Only
slight toe-in proved the best compromise for imaging and sound staging since
the speakers are not particularly directional.
The speakers
were coupled to the concrete slab floor with the high quality brass spikes
supplied by VSR. These produced the greatest increase in focus and sound
staging of any speaker I have ever heard relative to performance unspiked and floating on the carpet! CDs only were used as
source material through a Krell KPS-20iL CD player
run directly into the amplifiers through Harmonic Technology Truth Link
unbalanced interconnects. For some auditioning, Audio-Magic
Sorcerer balanced interconnects were used with the Krell
amplifier. Performance of the excellent 20-iL CD player was elevated another
few notches by an ElectraGlide ReferenceGlide
power cord. My reference speaker cables have recently become the top line
Harmonic Technology pro-9 copper cables bi-wired to the mid/tweeter and bass
modules of the VR8es. These cables afford new levels of detail and resolution
and fully deserve the accolades many reviewers have given them.
I also
recently obtained the highly rated Arcici Suspense
equipment rack (see review in this issue), which was used for all amplifiers (a
total of about 360 pounds!). The CD player was similarly placed on a BDR Shelf
for the Source with #3 cones and set onto the top shelf of the Arcici. I found that a mixture of #1 and #2 Vibrapods between the shelf and the top of the Arcici rack also provided an improvement in tonality.
Components were plugged directly into a Magnan
Signature power cord with strip, in turn plugged into a dedicated 30 amp
circuit. CDs were liberally tweaked with Compact Dynamics Optrix
spray on the playing surface and CD Upgrade discs, as well as Eco-3 antistatic
formulation sprayed on the label side. CDs were also routinely demagnetized
with the Bedini Ultraclarifier
before play and the Audio Prism CD Blacklight was
used. Yes, green paint on the edges of CDs made an improvement, and I have
evolved to the product from LAT, that does not smear when discs are treated
with Optrix. All of these tweaks gave audible
improvements that varied somewhat in degree, depending on source material. The
system was occasionally treated with the latest Purist Audio break-in disc.
Finally, monthly cleaning of all terminals on cables/interconnects/power cords
with ‘Pro Gold’ was beneficial.

This is a very good condition pair of VSR VR-8's in the dark cherry
finish. Not seeing much use at this point.
The original list price was $18,900. Looking for
someone local for these speakers as they weight 500lbs each. I do
have the original shipping crates and boxes, but prefer local pick-up.
Asking $9000 for this pair for local pick-up, for
shipping I will add $1000 + s/h costs. They are located in
Maryland for planning purposes. PM me for address and
other info if interested.
Stu’s Place:
Super Synergy! The Melos SE-75 & Von Schweikert
VR-8
Stu McCreary, with Mark Porzilli and Albert Von Schweikert
"I
don’t write unless I’m genuinely excited about something." That’s what I
told Positive Feedback Editor David Robinson when he was hounding me about
missing several installments of "Stu’s Place." The work load in my
legal practice and the fact that I do this for love, not money, had something
to do with it too, albeit a minor role. It really is true that I need a fire in
my belly to get motivated to write this stuff. In the past my motivation has
been great new products that deliver outstanding value for the dollar, like the
Golden Tube SE-40 or the Von Schweikert VR-4s. In a
few rare instances, it’s been a product that just hits a home run with me,
regardless of price, like what happened when I put the Blue Circle BC-2
amplifiers in my system.
In each case,
I’ve been keenly aware of how a new piece interacts with my bow tuning (that’s
system tuning, for you non-triode guild guys). I am fortunate to have many
tuning options in my system, such as switchable Tice power cords and movable Highwire Power Wraps. This has allowed me to accommodate a
lot of gear that on first blush I might have written off as sounding too lean,
or too fat. As I’ve worked my way through too many tube amps to count, I’ve
learned that the most important interface is the amplifier and the loudspeaker.
In fact, I’ve gone so far as to state that any tube amp review is really a
review of the amplifier and the speaker together. This interaction is so
critical and powerful, that normal tuning variables don’t often make the
difference — it’s either reasonably right straight off, or it’s not. Which
brings me to this issue’s installment of Stu’s Place — and yes, I AM EXCITED
ABOUT THIS or I wouldn’t be writing it! I’m going to share with you — no,
"share" isn’t quite right — I’m going to gush and blather about the
most incredible synergy of components I have personally experienced. So buckle
up audio nerds: this is going to be a no holds barred rave-a-roo! If you’re at all squeamish about this sort of thing,
I’d suggest you immediately re-read last months issue
of Stereo-snooze or Audio-snore.
Harmonic convergence or providential event?
It was fate
that brought the Melos HC 75 amplifiers and the Von Schweikert
Research VR-8 loudspeakers to my listening room at the same time. Here’s how it
went down. Over two years ago I wrote the world premier review on the VR-4
loudspeakers. About seven months after I wrote the piece, I got to meet Albert
Von Schweikert face-to-face for the first time, when
he and his wife Linda made a special trip to visit me. I learned that Albert
was considering a relocation and expansion and that he had looked at sites in
Texas and Florida. I suggested that he also consider Jefferson County, New York
(where I live!), and put them in touch with a friend of mine who was then the director
of the County Industrial Development Agency. The JCIDA put together a package
that Albert just couldn’t say no to, and another eight months later Von Schweikert Research was right here in my backyard.
Everything fell into place so easily that Albert and I both feel it was a
providential occurrence.
As I stated
in my original VR-4 review, I considered Albert Von Schweikert
to be a friend. At that time, he was just a telephone buddy I had never met
whose designs I greatly admired. Now that he’s my neighbor we have become
friends in the true sense of the word. We don’t talk shop all that much, but at
least twice a month we get together for a "Cars and ‘Gars" session.
Two grown men acting like the kids we really are — smoking hand rolled Hondurans
and yacking about our shared passion for fast cars.
One of the
perks of having a speaker manufacturer nearby is the receipt of the occasional
excited phone call — "Hey Stu, get over here, you’re not going to believe
the sound of this prototype . . . !" — which
inevitably draws me away from the doldrums of my legal practice and into the
listening room at VR.
Such was the
case with the VR-8s. Just days before they headed off to the
Winter CES, I was ogling them at the factory and getting a brief test run on
the sound. I was mighty impressed, but I refused to share my thoughts
with Albert until a proper evaluation could be done in my own listening room.
This is the leverage I needed to actually get these beasts over to my place. I
made Albert promise to bring them over when they got back from the show, and
true to his word, he had four guys from the factory grunting and groaning as
they wrestled the VR-8s into my listening room several weeks later.
The
circumstances surrounding the arrival of the Melos SE-75s weren’t quite as
obviously providential, but are still a worthy tale. I’ll try to be brief.
It was seven
or eight years ago, I’m not quite sure, when I was introduced to Melos by Dave
Carpe, a regular on The Audiophile Network (TAN) and quite possibly Melos’ biggest
fan. I was using the Meitner MTR-101 monoblocks at
the time with a passive Mod Squad Line Drive preamp, and was thinking that my
system sounded a little lean and threadbare. After hearing all the tube talk on
TAN and much about the mouthwatering midrange of the Melos gear, I decided to
buy a used 115B preamp through Audiomart. It turned
out to be just what the doctor ordered, ameliorating much of the threadbare
quality that disturbed me. Indeed, the chest register of vocalists returned and
cellos sounded like cellos again instead of violas.
Of course
being a true audio nerd, I wasn’t satisfied. I had the innate sense, like a
homing pigeon, that there was better performance to be had. So when I saw Dave
Carpe advertising his Melos 222C preamp for sale, I zeroed in on it
immediately. Dave got me salivating by telling me that his 222C had been
personally tweaked by his pal Mark Porzilli at Melos.
Mark was (and is) the brains behind the Melos designs — and we’re talking major
brains here. He was accessible and quite willing to talk to me about the preamp
design and some of the work that he had done to it. I was sold. The 222C proved
to be far more neutral and resolving than the 115B, and it held a place of
honor in my system for several years.
Last year I
received a review sample of the new Melos SHA Gold preamp. It was a honey of a
preamp, featuring the Porzilli Photentiometer,
arguably the best volume control in the world. I got the chance to talk a
little more with Mark Porzilli about his designs, but
being a modest and somewhat shy individual, I came away with a feeling that I
had only scratched the surface and that there was a lot more to Mark than was
revealed by our brief conversations.
During the
year I had the SHA Gold in house, I was frequently contacted by Mark or his
partner, Charlie Gavaris regarding the Single-Ended
scene. It seems that they had heard about my "Tube-Fest" series and
the many SE amps that had been through my doors, and the many more that were
still in my "on deck circle." Mark was developing his own SE amp with
a radical circuit and tube complement, and wanted to find someone with SE
experience to give his amp an honest appraisal. Charlie had suggested that he
drive up to my place, so that he could hear the competition at the same time I
got a chance to check out their offering. But being a little timid about our
North Country winters, he opted to have UPS brave the elements and tote the
gear. The SE-75s arrived in two massive boxes the same week the VR-8s arrived.
I was so
impressed by what I heard with these amps that I was motivated to scratch below
the surface and find out more about the unassuming Mark Porzilli.
I was amazed by the fact that when I initially contacted him regarding the SHA
Gold, Mark offered me very little about himself. I asked him if he had an
electrical engineering degree, and he just said, "No, I don’t" . . .and nothing more. I was left with the impression that Mark
was probably just a hobbyist who had learned a thing or two about analog
circuit design.
Little did I
know that I was really dealing with the Doogie Howser of high-end audio. You see,
Mark is such a humble guy that you have to bring a crowbar with you to pry out
the really interesting stuff. In his innocence, he hadn’t realized that
high-end audio is really a cult of personality, and that to be commercially
successful he needed to stop hiding his light under a bushel. Well now, I can
fix that. I’m just the guy to yank off the basket!
Mark "Doogie" Porzilli was a child
prodigy who was able to read circuit diagrams at the ripe old age of five. When
he was twelve he built a fully functional X-ray machine for a science project,
and by fifteen he had a college degree in physics. Mark is 39 now, and he
admits to only having made real friends in his adult years. You can just
imagine how difficult it must have been to relate to kids your own age
struggling over erector sets while you’re putting the final touches on a
machine that would have made Dr. Roentgen proud.
When I told
Mark that he was a marketing man’s dream come true, he laughed and told me that
"Porzilli" sounds more like something you’d
order at an Italian restaurant than the name of an audio innovator. He said, " I wish I had a name like Albert Von Schweikert. Now that’s a name with real substance."
Mark had read my review of the VR-4 loudspeakers and had enjoyed my Albert
Schweitzer, Albert Einstein, Albert Von Schweikert
association. I went to the fount of marketing slogans, our own PF advertising
sales manager Rich Brkich, and he helped me cook up
something with just the right Italian flare. How about
"Marconi, Vivaldi and Porzilli."
Give this guy some time and the proper resources and I’ll bet he’ll make a mark
on music reproduction like these other great vowel-on-the-end guys have. My
guess is that the photentiometer and SE-75 is just
the tip of the iceberg.
Albert Von Schweikert and Mark Porzilli are
a lot alike. They are both so brilliant in their chosen field that they get
lost in it, and sometimes appear almost absent-minded in other areas. It’s the
Albert Einstein phenomenon — so focused and deep in thought that you sometimes
forget to tie your shoes or balance your checkbook. I gravitate towards people
like this. I guess its
because I too have some of these qualities — though the brilliance is
debatable.
What can I
say? It’s very cool to see a small audio community begin to form right in my
own neighborhood, so I’m working on getting Melos to move up here too! Mark’s
got that child-like spirit and the twinkle in his eye, so I know he’ll fit
right in with Albert and me, even though he drives an econo-box
and doesn’t smoke cigars (yet!). Just imagine what these guys could cook up if
I locked them in a room together and didn’t let them out until they’d produced
something revolutionary. How about a custom tri-amped loudspeaker with digital
crossovers . . . ? Hmmm . . . .the possibilities!
Let me stop
right here and ask to see a show of hands: How many of you have enjoyed the
preceding section about the people behind the gear and how I came to know them?
If you’re raising your hand, great! You’re my kind of audiophile, and you’re
welcome to call or e-mail me any time to talk shop. If ,
on the other hand, you glossed over it and went right to the sections on how
the gear sounded, then you may be in danger of losing your soul to audiophilia nervosa, or its vicious twin audiophilia pomposa — or maybe
even (shudder!) to the great monster audiophilia assholea. ("The horror . . .the
horror!")
You see,
when the editorial group here at PF speaks about community in high-end audio,
we really mean it. We will always value people and our relationships above
hardware —way above. That’s why this magazine and its editor has no problem
whatsoever in publishing a piece where the principal reviewer — me — has a special
friendship with the manufacturers. We expect this sort of thing to happen and,
in fact, we encourage it. We know that a good community cannot thrive without a
free and open interchange of ideas grounded in honesty. This just happens to be
the same fertile soil from which life-long friendships arise. So we embrace it,
openly acknowledge it and then tell it like it is — that’s our credo.
Technical
tidbits from the Boys themselves
Since I’m a
technically challenged individual, I thought it best to let Albert and Mark
spoon feed me on some of the highlights of their designs. Here’s what they
prepared for me, with only some minor editing on my part.
The Melos
SE-75 amplifiers
By Mark Porzilli
A
disquieting quiet permeated the SE amplifier laden rooms of this year’s Las
Vegas CES. The quiet? 10 WATT SE AMPLIFIERS! Let’s be
realistic. Music is dynamic. High/low/loud/soft, etc. Otherwise it’s just
noise. Test tones. Inane. Dull. Dead.
One alleged "engineer" actually asserted to me that his amplifier
could deliver a "really big 10 watts." Hmmmm….big watts. I had
better look that one up. I don’t remember the definition of "big
watts" as opposed to regular watts. Boy I’m getting old.
At the risk
of sounding pretentious, I truly believe that a well trained
monkey could build a 10 watt, SE amp and throw a pretty faceplate on it. And in
my opinion, unless one possesses a passion for solo piccolo, 10 watts cannot
properly reproduce music.
A speaker,
any speaker, presents a rather complex demand on the output stages of an
amplifier. But that’s why it makes sound. It reacts; hence it’s a reactive
load. When music is delivered into a reactive load, a distorted replica of the
previous driver movement is kicked back into the amplifier (electro-motive
force). This "back emf" is damped out by
the amplifier’s output current. The higher the current, the more thorough the
elimination of the back emf and the more natural the
delivery of the signal will be.
The design goal
of the SE-75 was not only the elimination of the crossover notch (as is all SE
amplifiers), but retaining the extremely low impedance and high current
necessary to accurately deliver music into a reactive load. This goal is
accomplished via two mediums. Firstly, the choice of tube
type. The deflection tubes used in the SE-75 are capable of currents on
the order of 3x a 6550 or KT88. These tubes are then driven G2 triode. The
linearity of G2 triode operation will quite frankly put a 300B or 845 amplifier to shame. The G2 drive affords an additional
benefit of unusually low impedance and the corresponding increase in power
bandwidth. Some reservations have been asserted about the ambiguities resulting
from the imperfect paralleling of multiple output tubes. This problem was
easily addressed through utilization of the DC currents of the
"unused" G1, effecting a self- accommodating "auto
matching" circuit.
The
resulting improvements in linearity, damping, bandwidth and reduction of 2d
harmonic distortion produces a clear, clean purity devoid of bloat or harshness
plaguing antiquated SE designs.
[Gee, I
think my chastising Mark about being too shy may have worked...I’ll call him
Mark "Pit Bull" Porzilli!!]

Von Schweikert Research VR-8 loudspeakers
By Albert Von Schweikert
Frequency,
phase, and transient response, including low distortion and coloration, have
seemingly been perfected in modern loudspeaker design. Yet "realism,"
the missing ingredient, has eluded even the most ambitious and expensive
systems. Initially, I thought that extreme clarity would provide this
ingredient, and exotic drivers were utilized with lighter, stiffer diaphragms
made from woven carbon fiber and titanium. However, although enhanced clarity
did provide a better "window" to the performance, it alone did not
provide this missing element.
Several
years ago I became interested in developing a speaker system of high efficiency
suitable for use with very low powered amplifiers and "rediscovered"
the effects of high dynamic range. As the magnet strength was increased and the
diaphragms lightened further, the drivers sounded more "alive" due to
the actual clarity increase combined with the effects of increased dynamics.
Minute details veiled by low and medium efficiency transducers were brought out
in full relief. The heightened dynamic range also resulted in a very high
excitement factor.
However,
when combining several drivers which seemed to have promise, I discovered that
the enclosure and crossover circuitry had to be developed in parallel with the
transducers, not as an afterthought. The dissipation of low level detail by
enclosure vibration and circuit absorption had a very deleterious effect on
realism.
I have
termed this dissipation of low level signal information The Masking Effect, and
the resulting design of the VR-8 seeks to achieve the missing realism by
eliminating low level dissipation.
A
significant portion of the driver’s energy is absorbed, hence destroyed, by the
medium-mass enclosures of typical high-end construction, since the moving
diaphragm can either convert the energy of the electrical signal into sound
waves or cabinet vibration. Dramatically increasing the enclosure’s mass has
the effect of providing a non movable foundation
which in turn allows very subtle diaphragm motions to be heard. The increase in
low level detail adds a "breathiness" which I found very captivating
and high in the realism quotient.
Next, I did
research on typical crossover circuit components and found that normally
accepted dissipation in even expensive film capacitors and air cored inductors
was absorbing far too much low level detail. Several months were spent testing
all available capacitor types, including the most expensive aerospace units not
generally available. Amazingly, the best performing units were
"ancient" can-type oil filled paper units, dating back to the
beginnings of radio. Not surprisingly, these are the same type of caps used in
the $78,000 Audio Note Ongaku amplifier, generally
accepted as a "milestone" product.
Further
research into wire and inductors led to our design of a proprietary solid core
wire, featuring extremely high purity and a foamed Teflon dielectric covering.
This wire permits very low level detail to be easily heard, as the reactive
effects of inductance, resistance, and capacitance are minimized.
In addition
to the specially designed electrical components and wire, the actual circuit
topology is of innovative design. My Acoustic Inverse Replication Tm (A.I.R.)
radiation pattern is employed, since the goal of a true reference loudspeaker
is to radiate the signal back into the room in the same manner as the recording
microphone picked it up. In conjunction with the Global Axis Integration NetworkTm, my name for the special circuit, the A.I.R.
design allows a very wide dispersion pattern to develop. Listeners can sit
virtually anywhere in the room and hear excellent stereophonic imaging, even
when standing in between or behind the speakers.
The VR-8
system has been dubbed "an unlimited performance system" since every
aspect of it’s design and
construction has been engineered to provide the ultimate sense of realism.
Musical information simply dissipated and "lost" in other systems
comes alive. For instance, full bass response and wide sound stage imaging is
available at whisper volume levels. The VR-8 has a sensitivity of 96dB, making
it at least 3 times more efficient than most planar speakers. This efficiency
gain is similar to increasing the amplifier’s power from a few watts to
hundreds of watts.
Since
dynamic range is now heightened to very dramatic levels, low level detail is
"magnified" and crescendos are rendered to very high volume levels
without a trace of distortion or strain. Frequency bandwidth has been extended
at the same time, with an available response from 16Hz to 40kHz.
Coloration has been reduced to imperceptible levels, as the driver technology
is at the state-of-the-art level. Woven carbon fiber fabric is employed in the
twin midrange drivers, while oxidized titanium is used for the tweeter
diaphragms. Each enclosure weighs close to 500 lbs
due to the use of critically braced MDF from 1" to 3" thick. Recommended
power is from 7 watts up to one kilowatt. Impedance is 4 ohms with very little
variation. The Midrange/Treble unit is adjustable for vertical angle and is
Time Aligned, providing the ultimate in depth and
imaging.

So How do they sound, already?
I’m going to
talk a little bit about the individual sound characteristics of these
components, but keep in mind that I’m really evaluating them as a system. Both
are outstanding performers in their own right, but if you use them separately,
your results may differ from mine.
I started off
using the Blue Circle BC-2 amplifiers with the VR-8s on the first day they
arrived. I am much enamored with the Blue Circles and I have found them to be
my personal favorites with the Von Schweikert VR-4s
and 4.5s. It stood to reason that they should also perform well with the VR-8s.
They did in fact sound pleasing, but it wasn’t exactly magical. I was
concerned, given the height and overall size of the VR-8s, that they might not
disappear as well as the 4.5s in my 14’x29x8 listening room. Much to my surprise,
they did the same vanishing act as the 4.5s, but with a taller soundstage- the
perspective had changed so that I looked up at the stage as if I were seated in
the orchestra pit. This was not my familiar or preferred perspective, so I was
a little uncomfortable with the presentation.
I suspected
that the 4 ohm nominal impedance of the VR-8s was not an optimal match for the
Blue Circles. The VR-8s specifications recommend the use of high current tube
or solid state amps and it was quite likely that the BC-2s did not have the
juice to really make them sing.
I should
digress for a minute and let you know why this is a 4 ohm speaker when most SE
fans are dying for high efficiency and high impedance. Simply stated, the
design decision was based on sound quality, not SE compatibility. Early in the
design phase, Albert had intended to use a single high efficiency midrange
driver in the head module along with the inverted dome Focal tweeter. One
highly regarded (and recommended) midrange driver was selected as the best
candidate. It had superlative measurements; however, when Albert listened to it
with direct mic feeds in a prototype model, he concluded that it was far
inferior sonically to the Audax woven carbon fiber
drivers he was using in his other speakers. So much for
"foobie dust." Albert let me compare
these drivers first hand at the factory, and I absolutely agree with him. The Audax sounded much more like his real voice and guitar than
did the alternate driver.
The head
module design took a major turn as result of these findings. Instead of a
single high efficiency midrange driver, Albert was compelled to use two of the Audax drivers to achieve the same efficiency. The sound
quality went way up, but the nominal impedance went down. Fortunately, this isn’t
a problem for many tube amps. The impedance plot of the VR-8s is quite level
with only a small, gradual dip to three ohms. A tube amp with modest current
capability and a 4 ohm tap should have no problem with it. I can attest to
this, because in addition to the Melos SE-75, I had excellent results with the
28 watt Caztech SE-845s set on their 4 ohm tap.
Digression
ended. Back to the tale . . .
The next day
I hooked up the Melos SE-75s on their 4 ohm taps and was positively freaked
with the results! The soundstage height was now the same as the mid-hall
perspective on the 4.5s (spot on, in my opinion), with a vivid and incredibly
deep panorama of performers laid out before me. It was stunning. I didn’t think
I would hear much better than the 4.5s in this department, but here it was:
unmistakable, undeniable. Adding to the sense of realism,
was a crystalline clear, unfatiguing presentation of the most subtle of
atmospheric cues. It was as if I could sense the waves of rarefied air
emanating from the instruments and follow their paths
as they filled the venue and careened of its walls.
I was
listening to my favorite soundstaging disc, Kallen Esperian, American
Treasure, Pro Organo #CD 7047 (1-800-336-2224) and
was hearing new treasures on every cut. There was more, more, MORE of
everything. I was excited, REAL excited and I had to share this. I got on the
phone with Albert and ordered him to "get over here NOW!….don’t
wait, drop what you’re doing and get over here….you’re not going to believe
this." Albert arrived about twenty minutes later and I cued up "Going
Home." As the track ended and the hall sounds trailed out to what seemed
like infinity, Albert turned to me and matter-of-factly stated, "that’s the most incredible sound I’ve ever heard." Our
mature composure quickly melted away and we began talking rapid fire about what
we were hearing, like two kids who’d saved up their allowance for months and
were now playing with the neatest toy imaginable. "Wow, we’re hearing the
full potential of the VR-8s here . . .Did you hear
THAT?! Oh my god . . .we’ve got to get a pair of these
amps for the factory . . ." We played many of our favorites including
Diana Krall, All for You, and Sarah McLachlan, The Freedom Sessions
for vocals; Holly Cole, Temptation, and King and Moore, Impending
Bloom for Acoustic Bass; and Chesky’s Mozart,
The Flute Quartets for lilting breathy flute tones and plucked strings. The
more we played the wider our smiles. Half the time I was just giggling. Yep, It was that good.
I think it
was a combination of excitement and relief that touched off this reaction. Excitement over the extraordinary fidelity and holographic stage
that enveloped us, and for Albert, relief that his toughest critic shared his
belief that the VR-8s had surpassed all his previous work.
Much the
same experience was repeated a few weeks later when VR’s sales manager, Dave Kersh, brought over two audiophiles who had made the
sojourn to the VR factory from Canada and Connecticut. Dave had entertained
them that morning at the factory listening room, and called me to see if I
wouldn’t mind letting them hear the VR-8s in my system. Our Connecticut guest
had brought along his favorite test tracks, so I let him kick off the session
with his own selections. We were all dead silent for about 45 minutes and then
the superlatives started to flow –"I’ve never heard that before and I’ve
played that track hundreds of times"…. "Incredible"….."the best rendering I have ever heard…." It was like
Wayne and Garth on their knees chanting, "We’re not worthy, we’re not worthy!" It was particularly gratifying for
me to see this reaction in others. It let me know that my own experience was
not hyperbole or the result of audio incrementalism
that blows the smallest of improvements way out of proportion.
The VR-8s
let through more detail and ambiance cues at the low to moderate listening
levels I favor than any other loudspeaker I’ve heard. This was NOT accomplished
by an exaggerated, rising top end — a cheap trick that too many high-priced,
high hype loudspeakers use. No, the frequency spectrum was well balanced from
whisper quiet to ear splitting crescendos. There was loads of air and startling
detail without an ice pick in sight or any nails on the black board.
The
contribution of the SE-75s must be acknowledged here too. These are ultra-high
resolution, ultra-low grain, ultra-smooth,
ultra-holographic amplifiers. There have been a lot of amplifiers through my
doors (over 25 when I stopped counting), and at least nine of them have been SE
designs. Only the Blue Circles have shown this same level of grain-free, etchless (is that a word?!) detail coupled with startlingly
natural soundstaging. I don’t recall any other
all-tube designs achieving this level of performance.
I am quite
simply astounded by how well the SE-75s render the hall, the stage and the
individual performers. I know this is an inherent quality of the amplifiers,
because I listened to them on some more modest loudspeakers and all the signs
were still there (VR 1000’s, the least expensive of VR’s home theater line, if
you really must know). You pair these babies up to soundstaging
champions like the VR-8s, and you’ll be getting that hair standing up on the
back of your neck. You’ll probably be standing up too, like I did on several
occasions, to applaud along with the crowd.
About This Soundstaging And Imaging Thing...
Given the
grief that many of us soundstaging, imaging
aficionados have taken of late, I was pleased to learn that these are
characteristics that both Mark Porzilli and Albert
Von Schweikert hold dear. It’s really no surprise
when you listen to their respective products. But what IS surprising is that
both of these guys have the same sense of what constitutes natural imaging and soundstaging as I do. I’m going to digress again, but this
is really too important for me to pass up, so please bear with me.
I see two
very different schools of thought or experience that have
developed in this area of imaging/soundstaging. Well
actually three, but the third school is the one that discredits imaging/soundstaging almost entirely as some cheap simple-minded
affectation that has little, if anything, to do with our musical experience.
That school, led by a few high-brow stuffed shirts, is so foreign to me that
I’m not going to deal with it at all. In my opinion, the two schools that merit
discussion are the ones that do think that imaging and soundstaging
are an important part of music enjoyment. I call these two the
"Natural" school and the "Surreal" school. I guess my labeling
shows my bias already.
The Surreal
school is populated by far more audiophiles than the natural school. A sad, but
I think explainable situation.
The Surreal
group exalts what I believe to be a form of imaging and soundstaging
that does not exist in nature. It is a mutation that has arisen only from the
toxic amalgam of the typical hi-fi system in the typical listening room
environment. It is imaging that many of us "naturals" call
"cardboard cutouts" — the kind of presence on the stage that is flattened
and has an almost distinct edge, where the soundfield
of the instrument or vocalist abruptly ends and the black backdrop begins. You
can often tell that a reviewer is a surrealist when he extols the virtues of
images appearing out of nothingness, or an absolute black void, or when they
write something to the effect of — "the images were so sharp I could
practically cut my finger on them..." The surrealist’s stage is a group of
these cutouts all lined up on a black felt backdrop. The staging prowess of the
system is measured by how many cutouts you can count from left to right and
from front to rear.
Now, I ask
you, when was the last time you were at a live performance of a chamber
ensemble, orchestra or choir and got the sense that the performers were hanging
in a black void, or titillated yourself by closing your eyes and counting how
many distinct voices you could identify on two axes. Those of us who do
experience a good deal of live acoustic music know that there is no black void.
The space around and between the performers is rife with lower level sound I
like to call ambiance cues. A lot of this may be secondary, tertiary or even quatranary reflections of original sound sources. In terms
of left to right and front to back differentiation, us
naturals know that the direct radiated sound from performers expands outward
spherically and overlaps those of adjacent performers. If the pockets of sound
are too separate and distinct, missing the overlap, it is disturbing and
unnatural.
A naturalist
reviewer will likely talk more of the "spherical’ or
"cylindrical" qualities of the images and about a sense of the space
or atmosphere of the hall. The images they admire are still solid and palpable
at their centers. They’re just not hard edged.
Since I’m on
a roll, I’ll venture a few more generalities to stir the pot.
Not being
grounded in the live music experience, surrealists tend to gravitate towards
the flashy, hi-fi spectacular qualities of their systems and that usually means
exaggerated bass response, hyper detail from rising treble response and bloody
fingered, ultra-sharp edged imaging. The stereotypical surrealist system will
consist of a push-pull solid state amplifier with a healthy amount of feedback
driving a non-time and phase correct, limited dispersion loudspeaker. I believe
that these types of systems mask, erase, or obscure much of the ambient cues
that appear around and between the performers.
The
stereotypical naturalist’s system will consist of a low or zero feedback tube amplifier, that may be an SE design, driving a time and
phase correct broad dispersion loudspeaker. These systems excel in preserving
or perhaps enhancing the ambiance cues. I include "enhance" because I
have no way of knowing whether these naturalist systems are actually letting
through more of this information or whether it is some form of distortion or
artifact that I think is real ambiance information. It is sort of like the
argument that some digitalphiles use against analog
lovers — that turntables and cartridges introduce a form of white noise
distortion that for the analog lover makes music reproduction sound more
natural. Regardless of the cause, I believe that the naturalist systems sound
far more, well..."natural" than do the surrealist systems.
If I were to
establish a benchmark for a naturalist system, at this point in my journey it
would have to be the Melos SE-75/Von Schweikert VR-8
combination.
I know some
reviewers who have surrealist systems, and I don’t give any weight at all to
their opinions on amplifiers and loudspeakers, because I know that generally
what they like, I don’t. I’m not disappointed or hurt when one of my reviews is
followed by one of theirs and SURPRISE, they criticize
a product that I praised to the sky.
One such
reviewer and friend of PF is Martin DeWulf,
publisher of Bound for Sound. In the March issue of his mag, he states:
".....if you are in any way conversant with real music played in actual
acoustic space, an SE based system sounds little like it — though I’d be hard
pressed not to acknowledge that in some ways it can sound musical and pleasant
to the ears. But the constantly overlying sonic signature that one hears with
SE gear gets tiresome real fast. Again, it’s all right to desire SE, as long as
we don’t delude ourselves into thinking that the road to absolute transparency
lies that way."
Amazing,
isn’t it? Two reviewers whose viewpoints couldn’t be more
diametrically opposed. But are they really? Viewpoints are drawn from an
individual’s limited set of experiences. I don’t know what SE amps, other than
the Blue Circles, Marty has listened to, and I don’t know what loudspeakers he
used (absolutely critical, in my opinion), the acoustics of his room, or his
music preferences. What he heard in his listening room may well have sounded
dull, lifeless, rolled off and bass bloated. All that I can say with any kind
of authority is that in my room, with my associated equipment and listening to
my music, the performance of several SE amps and most notably the Blue Circles
BC-2s and Melos SE-75s sounded nothing like the above. I do find it
interesting, however, that Marty doesn’t seem to concentrate as much as I do on
the differences in imaging/soundstaging
characteristics. His focus seems to be more on frequency response and dynamics.
The moral to
this story is that wildly different opinions exist amongst those who review the
hardware and readers should never, and I mean NEVER, rely on reviewers to make
their purchasing decisions for them. I can’t take off my Stu-colored glasses to
make absolute, universal audio proclamations. I can only offer my opinions
based on my own limited set of experiences. Those experiences may well include
unique, unreproducible circumstances and may even be.....gasp....affected by
the friends I keep. You just never know.
I’d better
bring this back home... and what better way then to
simply say that Mark Porzilli and Albert Von Schweikert are both hard core naturalists. These products
are so uncolored and distortion free, that thier
awesome soundstaging characteristics stand out all
the more.
I had Greg Siriani, a world class operatic tenor and audiophile, over
for a listening session a few weeks ago. I played for him Kallen
Esperian, American Treasure and Telarc’s
Divine Sopranos expecting him to comment on the tonal qualities of the
vocalists, since he had sung on stage with most of them. Much to my surprise,
Greg’s comments focused almost exclusively on how much my room sounded like he
was sitting in the hall during rehearsal. On further questioning, he
acknowledged that he had heard some systems that got the voices right, but
rarely, if ever, had he heard the entire hall rendered so accurately.
I see a
logical progression in the Von Schweikert line. The
standard VR-4s are excellent speakers in their own right, but are the most
forgiving of the VR-4, 4.5 and 8 series (I’ve left out the VR-6s purposely
because I haven’t had them in my room yet). The 4.5s have greater mid-bass
punch and low bass definition as well as a finer resolution from the midrange
on up. I really didn’t think it could get much better than the 4.5s, but the 8s
are definitely a step further on the continuum to the real thing. As is so
often the case with this maddening hobby, you don’t understand, appreciate or
even conceive of what is better until you actually hear it first
hand.
The level of resolution of the VR-8s make them the least
forgiving of the lot. But the time taken to tune and refine the rest of the
system reaps from them greatest rewards. The VR-8s are capable of prodigious,
tactile bass if mated with the right amplifier and fortunately, the SE-75s were
up to the task — taut, but not too dry, and no confusing a bass drum for a
de-tuned tympani. I think the outstanding bass performance of the SE-75s is
attributable to its high current capability and its low output impedance. I
didn’t get the specs from Mark on this, but I’m told that the output impedance
of these amps is lower than typical tube amplifiers, and several orders of
magnitude less than typical SE tube amps. Nothing is more frustrating than an
amp that has a gorgeous midrange and a silky smooth top-end, but no bass
control. This is often the case with SE tube amps driving anything less than
huge 16 ohm 100+ dB/Watt/meter horn-loaded speakers. Not so with the SE-75s.
This is excellent bass performance for any type of amplifier, but for an SE
tube amp, its unheard of! A few of the tubed SE
amplifiers I’ve had here have had decent to good bass: these include the Manley
SE/PP 300B, the BAT VK-60’s (quasi single-ended), the Cary SE301, the Golden
Tube SE-40 and 300B. But so far only the hybrid Blue Circle BC-2 and the solid
state Pass Aleph 2 have had the kind of bass control exhibited by the all tube
SE-75.
The midrange
performance of the VR-8s is quite similar in character to the 4.5s. No surprise
here, since the VR-8 uses two of the same Audax woven
carbon fiber drivers used in the 4.5. Yet the VR-8s convey significantly more
information at low to moderate listening levels and are a notch above the 4.5s
in overall resolution and transparency. I would attribute these affects to the
higher efficiency of the VR-8s and the massive build quality and isolation of
8’s mid/treble enclosure.
The treble
is another story. The VR-8s inverted dome Focal tweeters are far superior to
the modified Vifas used in the 4 series. The top end
sounds that much more extended an airy on the 8s....and OH, that effortless
detail! I played one of my favorite tracks for top-end detail — the "Glass
Hall" (track 3) on Andreas Vollenweider’s White
Winds and Whoah!....those
glass gongs and bells filled the room with crystalline shards. For the first
time I was absolutely certain I was hearing rung glass and not tiny metallic
triangles. Massed strings had the right air and sweetness too. New life was
breathed into my not so old war horse Corelli, Concerti Grossi,
by McGegan and the Philharmonia
Baroque Orchestra (harmonia mundi). I actually sat
transfixed for a full hour as if I were soaking in a brand new performance.
Integration
of drivers is often an issue on very tall loudspeakers. I’m happy to report
that, despite the nearly six foot height of the VR-8s, and in spite of the fact
that I was sitting a mere seven feet back, you can’t distinguish the driver
source. This is one of the hallmarks of a Von Schweikert
loudspeaker. You can stand up and walk around and you won’t notice any
appreciable timbral shifts. The same goes with the
soundstage — it stays put, even when you don’t. I’d call it a tie with the 4.5s
for these characteristics.
The Melos
SE-75s are the perfect match for the midrange and top end performance of the
VR-8s. These amps will not obscure any of the speakers’ clarity. They have
outstanding bandwidth and are utterly devoid of inherent glare, harshness or
etch. They breath almost organically with the music —
the right amount of air, body and sweetness. Never bloated, carmelly or sappy-sweet. All that I have said about
the sound of the VR-8s is equally attributable to this magnificent amplifier.
I hoped that
I wouldn’t soon get used to this new level of airy detail and ambiance
retrieval — it was just too damn fun! I only have about a hundred disks that I
truly consider to be my time tested favorites. At the rate I was burning
through them in the first week with the VR-8s and SE-75s, I thought I’d be done
before the month was out...and I nearly was on that angst-filled day when the
boys from the VR factory arrived to take the 8’s away (sniff, sob...!).
As I
mentioned previously, the VR-8s are the least forgiving of the VR speaker
lineup. This level of clarity, extension and detail should not to be squandered
in a half-assed system. Same goes with the SE-75s. You could definitely get
them to sound harsh, if your front-end or source
material sound that way. Fact is, if you want everything to sound milk toast
pleasing, you’re not going to want to own the VR-8s. There are a number of polypropelene-midranged, fabric-domed-tweetered
"homogenizers" that I could recommend for this. The problem is, if you go the "always pleasing" route, you will
never experience the sublime. Play a world class recording like Kallen Esparian’s American
Treasure on a system like the one currently on loan to me and you’ll KNOW what
sublime is. If you don’t cry or shout for joy, you’d better back off on the Prozac.
Conclusions
The Melos
SE-75s and Von Schweikert Research VR-8s are
milestone products by two of the most brilliant and original thinkers in
high-end audio. I have come to expect great things from them and, once more,
they have exceeded my expectations. I have to thank them for getting me excited
enough to get over my writers’ block.
I’m cleaning
house to make room physically and financially to own both of these products for
my reference system. The synergy is so incredible that I don’t think I could
bear to be without either of them. If you’re a naturalist like me, Mark, and
Albert, you’ll go nuts over this system and probably find some way — devious or
divine — to own them. You have been warned . . . .
And how’s
that for a Rave-a-Roo?!

Research
(MK comments) Let me give you a mental image...kid in a candy store. Okay?
Got it? Picture room upon room of high end gear just waiting
to be heard. Wiping the drool from my mouth I went looking for audio
nirvana.
I'm not going to bore you with an account of every room I went in, but I
want to give you some of my personal highlights from the show.
Albert Von Schweikert showed off his latest speaker,
the VR-8. This extremely large floor standing speaker (65"H and 500 lbs.
each) has six drivers, looks massive, and has a 96dB sensitivity. Single-ended
tube lovers will crave this speaker. The only problem is that you need a big
room and lots of cash, $17,000 worth. As to their sound, I was impressed,
although I think they were way too much speaker for the room they were in. Von Schweikert also had a smaller room where they had a
surround sound music presentation using their new VR Theater speakers. The
sound was excellent, even though the music they used was horrible. One thing I
can't get used to is this whole concept of being placed "in" the
music. It was disconcerting to hear a voice singing behind me on the left. I
kept thinking that Mike Fenech was singing in my ear.
Weird.
(DAS adds) They grow 'em BIG in upstate New York.
I don't think we'll see a review sample of these babies in my one bedroom
apartment soon. Physically, the VR-8's are overwhelming. But if you've got a
large room and just under 20G's to drop these may be
your ticket to sonic paradise. It is obvious that this is intended to be VSR's
'statement' loudspeaker. I don't have $17,000 to spend, nor the room, but a
number of people do and these may be considered a bargain loudspeaker in those
circles. BTW, I thought it was Mike singing too! Sh'eesh,
maybe it was.....he has a nice voice.
