During
my travels in and
around NYC, I
happened to run
across a new audio
store called
"In Living
Stereo,"
located at 13 East
4th Street, in
Greenwich Village.
You may ask why
this in itself is
notable but, given
the trend over the
past few years of
high- end audio
store closings in
this area, I think
it is a big deal.
This is a small
store that
features products
by Epos, Creek,
Music Hall and
Straight wire.
They have an
abundant supply of
very good
entry-level gear.
Moving up the
line, you will
find the new amps
from the French
manufacturer Kora.
Given their sonics
and visual appeal,
I think that you
will be hearing a
lot more about the
Kora line of
electronics in the
near future. The
store's top shelf
offerings are from
Conrad Johnson.
Of
particular
interest were the
Gibbon ll
loudspeakers by
DeVore Fidelity,
or DeF for short.
These are a small,
stand-mounted,
two-way design
that produces a
very large sound
with a surprising
amount of low-end
extension, given
their diminutive
size. I hope to
get back to
"In Living
Stereo" very
soon for another
listen to some of
the other speakers
in the DeF line. I
would suggest
that, if you are
ever in the area,
drop in and pay a
visit. I wish them
all lots of luck.

Recently
I came across
several products
that I think
deserve a closer
look. Roy Harris
is a friend and
someone that I
consider a true
golden ear. During
a conversation, he
told me that he
had the Bruce
Moore Companion
IIB in for a
listen. He was
aware that I had
reviewed the
Companion III
preamplifier and
thought that I
might like to give
the IIB a listen
as well. I agreed,
and soon after,
the proverbial box
from UPS arrived
and the listening
began.
Having
fond memories from
the time spent
with the C-III, I
rather expected to
be somewhat
disappointed with
the sound of the
IIB by comparison.
Well, right off
the bat, I was
quite pleasantly
surprised by what
I heard. Before I
go any further,
there is one
caveat that I must
bring up. Because
this line stage is
phase inverting,
you must be sure
to reverse the
speaker terminals,
either at the
power amp or the
speaker. Don't
misunderstand me,
nothing will blow
up nor will your
system crash if
you fail to do
this. However, you
will not hear the
best that this
unit has to give.
The
Companion IIB is
positioned at the
bottom of the
Bruce Moore line.
Priced at $1,650,
it is not very
expensive for an
entry-level tubed
line stage.
Cosmetically it
looks very much
the same as the
rest of the Bruce
Moore line. The
volume controls
are clutched
rather than
stepped as on the
C-lll. While the
dual volume
controls give you
a balance control
at the same time,
I find that these
controls make it
more difficult to
set the balance
correctly. I would
opt for the more
expensive
Goldpoint controls
that negate this
problem and should
deliver a sonic
benefit at the
same time.
Once
I patched the C-llB
into the system, I
found the sound to
be quite pleasing.
I would judge the
tonal quality to
be warmer than its
larger sibling.
Its sound staging
abilities, along
with its rich
tonal
presentation, let
you know that you
are listening to
tubes. Where it
falls short of the
C-lll is in its
openness and
delicacy. It lacks
a good deal of the
air and high-end
extension that the
C-lll readily
exhibits. The C-lll
is more detailed
overall and is
better at
resolving low
level details. An
example of what I
am referring to
can be heard with
female voice. The
"Menuet pour
la petit gnomide",
from Marc
Antoine
Charpentier,
Divertissements
Airs et Concerts,
William Christie
Les Arts
Florissants, [Erato]
features a
beautiful soprano
solo that is a
real test for any
system. With the
C-ll, there is a
slight loss of
extension here.
Unless you compare
this line stage
with a much more
expensive one, you
probably will not
notice it.
While
the C-llB falls
short in these
areas, I don't
mean to say that
it is, in any way,
bad sounding.
These are
attributes that
you only miss in
comparison to the
much more
expensive line
stages. When taken
in total, I have
to say that I find
this to be a
musical sounding
unit. When given
the choice, I
would rather
contend with
errors of omission
as opposed to the
other way around;
fortunately that
is the case here.
Of
course, as luck
would have it,
while putting this
article together,
the C-llB has been
upgraded to the C-llC.
The changes
include the
substitution of
Cardas connectors
as well as a
detachable line
cord. There are
circuit changes as
well as an upgrade
of capacitors and
resistors. I am
particularly
grateful for the
upgrade to the
volume controls.
The previously
optional Goldpoint
stepped
attenuators are
now standard
issue. In addition
to the better
attenuators, the
red power light on
the llB has been
changed to blue,
making it easy for
consumers to tell
the difference
between the older
and newer models.
I think that the
new Companion llC
should be
something really
special. Stay
tuned for a full
review.

I
came across these
Golden Sound
products during a
listening session
at the home of
Marshall Nack. The
combination of the
cones and disks
made more than a
subtle difference
in his system. I
was curious as to
what effect they
would make for me
as we have
radically
different systems
and listening
rooms. At
Marshall's
suggestion, I
contacted Allen
Chang of Golden
Sound and shortly
afterward I had a
full set of their
treatment devices.
Starting
with the Acoustic
Disks, one set
will treat the
four corners of a
typical room. They
are the most
inconspicuous room
treatment devices
that I have ever
seen. The Acoustic
Disks come with a
template that
makes it very easy
to align and place
the disks in the
corners properly.
This is a very
easy and
straightforward
procedure that
should only take a
few minutes to
complete.
The
interesting thing
about room
treatments, and
isolation devices
as well, is how
much the results
will vary from one
system to another.
Since my room is
radically
different from
Marshall's, it
comes as no
surprise that my
results were as
different as our
rooms are.
I
found that the
disks generally
affected the
treble but to a
smaller degree
than Marshall
experienced.
Before installing
the disks, certain
vocal tracks and
some saxophones
would exhibit
hardness during
loud passages.
After installing
the disks, the
hardness
disappeared. Even
when listening at
louder volume
levels than usual,
there were no hard
spots, yet there
was no loss of
detail. This is a
pretty neat trick.
I found the other
areas of the sonic
picture were
unaffected by the
installation of
the disks.
Overall, I
consider the
effect on the
treble to be an
improvement.
As
with all things in
general, and audio
in particular,
when a little is
good, much more
seldom is better.
Since these disks
are so
inconspicuous
there is the
temptation to use
more of them in
other than the
corners formed by
the wall and the
ceiling. While
there isn't any
reason to restrict
yourself to use
the disks only in
the corners of the
room, remember
that the effect of
these devices is
cumulative - too
many of them will
dull the treble
and rob the music
of any life-like
qualities that you
may have. Feel
free to experiment
- add disks first
to the top
corners. If you
feel that you need
still more, then
start adding them
to bottom corners.
You can keep going
until you achieve
the effect you
desire. The
product literature
states that you
can also place
them mid-wall
behind the
listening
position, on top
of speakers and
amps, etc. These
disks are an
effective room
treatment device
and, at the price,
you can afford to
experiment.
The
cones and pads are
another story
altogether. The
product literature
states that the
cones should be
arranged in a
triangular array
under speakers or
electronics. As I
was using the
Eggleston
Fontaines with
their own
well-designed and
dedicated spikes,
I limited my use
to the electronics
only. The greatest
sonic change was
achieved by
placing the cones
and squares under
the CD player that
I was using as a
transport. When I
placed them
directed under the
player, all of the
mid to low bass
disappeared.
Curtis Lundy's
"Players
Anthem" from
the Against All
Odds CD [Just
in Time Just
129-2], opens with
a prominent bass
solo. After
placing the disks,
the upright became
thin and thuddy.
The bass drum
however, took on
larger-than-life
proportions and
became much too
loud. The
difference was
startling to say
the least.
During
a conversation
with Allen Chang
of Golden Sound,
he told me that
removing the pad
on the back of the
cone would make a
sonic difference.
I tried this in
addition to
repositioning them
under the
transport. The
result was not
only the return of
the sound with
regard to low-end
fullness, but it
was markedly
better. The low
end was tighter
with a greater
sense of
definition. While
I could hear more
texture with the
upright, the
effect was not
exaggerated.
Personally I find
the
"detail"
thing is too often
overdone. Overall
the sound opened
up, there seemed
to be more space
between the
instruments with a
corresponding
increase in the
focus. It wasn't a
jaw dropping,
freeze you in
place improvement
(these rarely
happen in the
high-end realm
anyway), but the
difference was as
noticeable as it
was welcome. By
adding the cones
under the pre-amp
and the power amp,
the same kind of
improvements were
made but to a much
lesser degree. The
greatest
improvement was
achieved by
installing the
cones and pads
under the
transport.
Given
the universe of
isolation devices
and room treatment
devices on the
market today, some
of them with very
serious prices
attached to them,
Golden Sound has
managed to come
out with some very
effective products
at very reasonable
prices. As always,
you have to
experiment since
they are room and
system dependent.
If you choose to
do so, I think
that your efforts
will be well
rewarded.
