Road trips,
even in middle age; I
still love 'em1
. But this was not your
ordinary consumption of
mass quantities,
hedonistic behavior road
trip. This was a
consumption of mass
quantities, hedonistic
behavior road trip to
visit an acoustically
like-minded reviewer,
Greg Weaver. While a
long time in coming,
this visit was still a
rather spur of the
moment decision.
For
many years, I've known
Greg to highly value, as
I do, the merits of
acoustically treating
the listening space. And
with some privately made
positive comments about
the new Von Schweikert
Audio VR-4 Gen. III
Hovland Special Edition
loudspeaker and Spectron
Musician II amplifier,
Greg had piqued my
interest. In turn, I
have been making some
noise about the Manley
Snapper monoblock
amplifiers and Portal
Panache integrated
amplifier that had
sparked similar interest
with him. The final
factor (and as everyone
knows, any worthwhile
road trip needs a
"deciding" aspect) was
that I would be taking
possession of this very
same loudspeaker very
shortly.
We decided then and
there2,
that it just may be a
fascinating and
worthwhile experience to
listen to a similar
assortment of equipment
in different, but
intricately treated,
environments. The chance
to hear a particular
piece of equipment,
especially a large
loudspeaker, in two or
more controlled
environments will
certainly allow for a
much more comprehensive
understanding of what it
is doing, and should
therefore result in a
much better review
accordingly. With that,
a change of clothes, one
pint of Glenlevet single
malt and some finer
tobacco, I was off!
Approximately an hour
into the listening
session, my visit had
drastically changed in
tone if not purpose. I
certainly was not
expecting this level of
performance3.
But what I was hearing,
and what was to follow,
was simply one of the
top five audio
experiences of my life!
Firstly, it was
fascinating to hear an
environment set up by a
different yet educated
ear. Using differing
acoustical tools and
theory, Greg's end
result offered much the
same sonic qualities as
my own room. While I use
Tube Traps and Flat
Traps arrayed about the
room in strategic
fashion, Greg uses foam
products configured in a
modified Live End-Dead
End (LEDE) set-up. The
main difference appears
in the reverberation
time of our respective
rooms. While I think I
may obtain a bit more
imaging precision,
Greg's room has a quite,
quite beguiling
"openness" at and behind
the listening position
that I would gladly
trade a bit of my
precision for.
The next difference is
in room-related bass
response. Greg's room is
a conventional
wood-framed living area
that vents into other
portions of the house.
The advantage of this is
the lack of severe
standing wave build-up,
with virtually no
masking of the vital
low-level midrange
signal. The downside is,
while there was plenty
of bass in the room,
there was a certain
amount of low-end "heft"
missing from the room
that I am accustomed to
with my room due to the
minimal room support.
Conversely, my room is a
basement, which can tend
to overly support
standing waves, causing
a lumpy, bloated bass
and the attendant
masking of the midrange.
Hence my heavy reliance
upon Tube Traps! I'm
sure Greg will have to
acclimate himself, as I
did, when he is exposed
to the bass response of
my room during his
upcoming visit. Oh, to
have the response "in
between" our two rooms!
Overall though, from the
midrange upwards, our
rooms are spookily
similar.
And what a different
animal the VSA VR-4 Gen
III SE is! While I
reserve final judgment
until I have the VR4 SE
in my room, I must say
that I'm not sure I have
ever heard a better top
end from any speaker to
date. So deep in ambient
trail, so pure and
uncongested is the upper
octaves of this special
edition VSA speaker. The
closest analogy I can
make is the wonderfully
creamy treble of the
ProAc line of
loudspeakers, but with
all of the detail one
should ever want4.
With the VR-4s spread
wide, they just seemed
to effortlessly put
forth a sonic vista that
at times totally removed
the room from the
equation. Coupled with
the Spectron Musician II
amp, this system played
any genre of music I
threw at it. Chet Atkins
was virtually in the
room with us. Some Yello
remixes I brought
threatened to pummel the
room into dust. And I
still cannot get over
what this speaker and
amp combo did for massed
strings! But the best
was left for last. A
remastered Dire
Straights LP with the
lights down low. Thanks
for that one Greg!
The Portal Panache
integrated offered a
rather good showing
also, keeping the same
basic tonality and
exhibiting a wonderfully
liquid midrange. The
Manley Snappers at first
fared less well.
Exhibiting a bright,
grainy presentation,
decidedly NOT what I
obtain from pairing them
with my Coincident Total
Eclipse loudspeakers. As
it had been about a
month since I had last
checked the biasing of
the tubes, Greg was
immediately at hand with
a volt meter. Sure
enough, all four of the
EL-34's in each chassis
were running a bit high
in the bias; several had
drifted as much as 30%
higher than optimal. Now
dialed in, it was a
completely different
amplifier. While not
quite being up to
driving the VR4's deep
into the bass, it
delivered certain
strengths in the
midrange that was
especially flattering to
close miked
performances, making
them quite special in
their own way5.

All
in all, this turned out
to be a fascinating
visit on many levels,
both for me personally
and my alter ego
hobbyist. Besides,
during the lunch break,
driving around town, I
decided it was pretty
cool to visit a guy who
tools around in his
aging Turbo Mercedes,
complete with compound
loaded subwoofer,
booming Beethoven as he
bombs down the road.
Entertaining an
Audiophile on a Mission
Greg Weaver
August 2002
When
Jon first said he was
going to be able to
visit, I was thrilled. I
hadn't seen him in quite
some time6
and, though I have many
friends here in South
Bend, none of them were
really seasoned
audiophiles. As I was so
excited by what was
going on with the
Von Schweikert Audio
VR-4 Gen III SEs
and the
Spectron Musician II,
I wanted to have someone
with a diverse
background give them a
listen and see why I had
been raving to all my
audio friends.
His arrival at 9:00 a.m.
that Saturday took me by
surprise, as I hadn't
expected him until noon.
But, by 9:45 the
Manley Snappers
were plugged in and
warming up. Jon sat
down, we hit the play
button and the game was
literally afoot.
Within about an hour,
Jon's look changed from
one of determination to
one of sheer delight and
slight confusion. He had
been sure he would be
able to cause the Gen
III SEs to falter. Yet,
try as he might, he was
unable to find any
significant flaw. "Don't
worry," he assured me,
"I brought lots of stuff
to trip 'em up."
When I pointed out the
differences between the
stock Gen III and the
HSE version, I could see
Jon was very interested.
First, the tweeter is
the new $450
Scan-Speak R2904-700000,
which is used in only
one other commercially
available loudspeaker at
this time, the $37,500
Krell LAT-1! To
say this is a special
tweeter would be an
understatement.
The SE version of the
Gen III substitutes a
cleverly modified Audax
Aeorgel midrange for the
Vifa/Scan-Speak that is
used in the stock
version. Albert makes
changes to the dust cap
and the resonating
chamber behind the motor
structure. The
differences are
dramatic, with
microdynamics now being
handled with a deftness
I've not heard in my
home before. There is a
tonal balance and a
purity here that is
indisputable. And talk
about resolution and
detail! This is one
seriously over-achieving
loudspeaker that has no
business selling for
$6,000. The VR 4 Gen III
HSE easily bests
speakers I've heard
recently in the $12,000
to $15,000 price range.
No joke! Ask Jon.
Well, after a good two
hours, it was time to
try the Manley Snappers.
Jon had told me that he
had not rebiased these
gorgeous looking
100-watt monoblocks that
are based on the EL-34
output tube since he had
gotten them, but we
wanted to see how they
sounded as they stood.
More than adequately
warmed up, we swapped
out the Musician II for
the Snappers.

The
first thing that was
evident was the superbly
delineated and recreated
midrange. The voices of
female singers, pianos
and violins were so
liquid and solid you
could just about touch
them. However, starting
in the upper midrange
and continuing on up
through he highest
frequencies, there was a
disassociated and grainy
texture. Bass, deep
bass, was almost
non-existent, and
midbass was slurred and
slow sounding. Time for
that fabled Volt meter!
Jon had forwarded me the
web site from the Manley
page that had the
biasing spec's for the
EL-34's, and soon we had
them all idling within
0.1% of the specified
275 mV, just as Eve Anna
intended. I must say, in
all fairness to the
previously noted
performance, each of the
4 EL-34's per chassis
had drifted at least 10%
high. Some were as much
as 30% higher than the
specified 275 mV. I
suspected that this
would have had an effect
on the amps overall
performance, but
couldn't have guessed
how much.
Rebiased and idling back
at factory spec, they
went back into the fray.
The resultant sound was
much better now, in
fact, it sounded like a
different amplifier.
Glass heads out there,
take note. Though the
amp sounded much better,
there was still an
unwelcome taste of the
grain in the upper
registers and no real
deep bass7.
Voices were now
recreated majestically,
piano, guitar and other
midrange voiced
instruments just
hauntingly portrayed.
Very seductive, but…for
this listener, not
enough so to give up the
extension at the lower
end and the finer
resolve in the upper
registers I have grown
used to.
Next up, it was time for
the $1799
Portal Panache
integrated amplifier.
Wow! This little guy
knows how to handle a
pair of loudspeakers. It
offers wonderfully
tuneful bass, nice, if
somewhat over-energized,
treble and has a
delectable balance. On
the downside, it did get
a bit congested with
complex material, but at
this asking price, and
with a preamp thrown in,
who could really
complain? Jon and I
stepped outside to take
a cigarette break and I
mentioned that the
Panache reminded me
sonically of the old
Forté 4. The Forté 4 was
a 50 Wpc amplifier8
that was built by
InConcert, a division
Threshold, the Nelson
Pass amplifier company
of the late Eighties and
early Nineties. The
Panache is a really fine
product, operating with
much of the definition
of its name. I know many
budding audiophiles who
will find this the
perfect way to start
their high-end odyssey.
Then, it was time to put
the Musician II back to
task. Jon tried for a
total of thirteen hours
that Saturday to fault
the Gen III SEs, and
while paired to the
Spectron, he just kept
scratching his chin and
putting on disc after
disc after disc. It was
a beautiful evening of
music, and I greatly
enjoyed the new music
Jon was introducing me
to. I really enjoy the
opportunity of having
someone drop by with his
or her own music; it
gives me a chance to
expand my horizons. I
have found it the best
way to grow my music
collection.
About 8:30, my cell
phone rang and it was
none other than the
creator of the Gen III
HSE, Albert Von
Schweikert himself. I
shouldn't have, but I
decided to toy with the
loudspeaker Maestro.
"Albert," I said, "Jon
doesn't like your SEs!"
"What?" he exclaimed. I
could hear the surprise
and tension in his
response. I couldn't do
it. "No, he doesn't like
them. He loves them!" We
both laughed and I
handed the phone to Jon.
They talked for a while,
and before the
conversation was over,
Albert promised that
Jon's pair, only the
second pair available
out in the real world,
would be on their way to
him the following
Monday.
We retired to my theater
after another hour or so
of listening to watch
part of one of my
favorite films, Bernard
Rose's Immortal Beloved,
which deals with the
mystery surrounding
Ludwig Van Beethoven's
death and last will and
testament. About 11:30,
I bid Jon goodnight, and
we called it an evening.
Jon was able to stay
some of Sunday morning
before heading home to
his family, which found
me hosting our local
group for our regular
Formula One party; this
week it was the eleventh
race of the season, the
French Grand Prix from
Magny-Cours. It was an
outstanding event in
that Michael Schumacher
won the race, clinching
his fifth Formula One
World Championship and
tying, for the very
first time in F1
history, Juan Manuel
Fangio's 45-year-old
record. It was history
in the making; much like
the Von Schweikert Audio
VR-4 Generation III SE
and the Spectron
Musician II. These are
two VERY SPECIAL and
noteworthy products
that, to this listener,
represent serious
milestones in my 30-year
travel toward higher
fidelity. Full reviews
coming on both. Enjoy!
1
I REALLY love to drive.
And I have yet to have a
vehicle with an
automatic transmission.
2 Actually,
it was deep into the
evening and a pint of
single malt that we
decided on this series
of articles. But I would
be getting ahead of
myself!
3 Of the
VSA models I have heard,
I have always put them
in the same category as
Theil. I respect them
from a distance, but
have never really loved
them.
4 And I
deliberately brought
decidedly un-audiophile
recordings! Figuring
Greg had the audiophile
thing covered, I just
brought my every day,
good time listening
records.
5 Review
coming soon, promise!
6 Jon and I
first met at the
Stereophile show in May
of 1999, though we had
appreciated each other's
work from afar for some
time.
7 It should
be noted that the
attributes I am
describing here are, in
my opinion, are common
to most tube amplifiers
in my experience. Not
all, but most.
8 The Forté
4 was the first amp that
utilized the
Insulated-Gate Bipolar
Transistor, known
colloquially as the
IGBIT.
