Best
to repeat at
the start
something I
mentioned
in an
earlier
appearance. I
edit a
webzine, La
Folia,
sponsored by
Madrigal Audio
Laboratories,
the
manufacturer
of Mark
Levinson audio
components. As
a music writer
for Fanfare
and The
Absolute Sound,
I first
purchased a
Mark Levinson
No.39 CD
player and
No.333 power
amplifier
before I
approached a
Madrigal
executive
familiar with
my Fanfare
work with a
proposal for
an online
music review.
The overture
was mine. A
tad
cyberphobic
(read: hapless
geezer), I
desired only
to provide the
writing,
recruiting and
editing,
surrendering
the webzine's
meat-&-potatoes
operation to
someone else's
care. The
folks at
Madrigal liked
my idea. A
music review
would help
attract
browsers to
their website.
Nevertheless,
the reader who
regards what
follows as
suspect must
not be faulted
for untoward
skepticism. I
can do no more
than assure
you: my
thoughts are
my own.
Nor
do these
thoughts
promise to
resemble
audio-hardware
commentary as
it normally
occurs. I
listen to my
sound system
as a totality
and find it
difficult to
discuss it as
an agglomerate
of parts.
Allowing thus
for the
inevitable
verbal
vagueness
attaching to
one's
experiential
unity, suffice
that I
perceive the
vastly more
expensive and
physically
imposing 33H
mono power
amps as
significantly,
profoundly,
astonishingly
better. Than
everything
this side of
breathing!
(One wants not
to overstate.)
Mind, I liked
the 333 very
much indeed.
We're really
talking about
conditions of
good to better
to best to --
oops! -- off
the chart. I'd
do well to
step back for
a moment, wipe
the foam from
my lips, and
describe
relevant
peripherals. I
had an old
Audio Power
Industries
Power Wedge
line
conditioner
squirreled
away in the
closet which
one day not
long ago I
decided to try
with the
digital piece.
Very nice: I
think perhaps
the noise
floor dropped.
When noise
floors
descend,
resolution
accrues. I
e-mailed Les
Edelberg, the
man who runs
API, to ask
him how
urgently he
recommends my
replacing the
old Wedge with
one of his new
Ultra Wedges.
He did not
say, You
absolutely
must! Yet,
subtle geek
that I am, I
peered into
the spaces
between his
comments and
decided that
yes, he really
was saying I'd
be much
happier with
the new line
conditioner.
I've lived now
with an Ultra
Wedge long
enough to
determine that
I am indeed
happier.
Relative to
that two other
tweaks: a
separately
offered
replacement
power cord for
the one that
comes with the
112 Ultra (the
model I
bought), and
an API power
cord I've had
on hand for
several years.
So then, we've
an API 313
Power Link
from player to
Ultra, and
from Ultra to
wall, an API
311 Power
Link. As a
final touch,
the player
sits on a
Bright Star
Audio
air-suspension
platform (a
shallow,
open-bottom
box atop a
silent poo-poo
cushion).
One
further tweak,
this to my
Wilson
WATT/Puppies.
Scot Markwell
of The
Absolute Sound
fashioned for
me a set of
Siltech
jumpers -- the
external wires
connecting the
lower Puppy to
the upper WATT
-- to replace
Wilson Audio's
own Puppy
Tail. Wilson
warns against
such
replacements,
since the
networked
Puppy Tail
acts as part
of the
crossover.
Caution noted,
I think these
Siltech wires
do one hell of
a job. My
cabling
otherwise is
Nordost SPM,
one pair
balanced
interconnects,
ditto speaker
cables. It's a
bare-bones
system: CD
player (with
good analog
level
control),
amps, and
speakers. I
live with my
wife, Lee, in
a small loft
in Park Slope,
Brooklyn.
Scattered
built-ins
appear to act
as effective
diffusors. Our
dwelling
encloses a lot
of wall art,
sculpture,
cushions,
pillows,
carpeting, but
no room
treatment as
such. People
find the
acoustic quite
good. High
ceilings help.
As
advertised,
one's thoughts
on the
Levinson No.
33H mono amp.
First in
importance,
I'm listening
to a system.
The tweaks to
the player are
in the mix, as
is the time of
day, one's
mood and the
music. At one
moment, an
especially
revealing
recording has
one's gear on
its best,
ultra-high-resolution
behavior, at
another, one
listens
(because he
must) to
something that
would sound
about as good
emitting from
a camel's
rump. Crummy
discs dwell
beyond help.
If your system
makes
everything
sound peachy,
you're up the
wrong
irrigation
creek. Very
well then,
these are the
qualities I
assign primarily
to the 33H:
The
issue is one
of truth in
music, or more
accurately,
truth in
recording. I'm
closer to the
heart of the
matter. More
than ever
before, a
superbly
resolved
soundstage
appears to
exist
independent of
the hardware.
I've a better
defined sense
of depth, of
coherence
within the
spread. That
elusive
quality of
soundstage
height seems
more
discernable
too. I'm
hearing a far
more
authoritative
dynamic, an
extraordinary
control over
transients,
however crisp,
brutal, or
startling,
along with a
better
delineated
sense of
dynamic
gradation:
diminutive
sounds stand
in clearer
relief. The
huge amp's en-pointe
finesse is
perhaps what
would most
impress were
it not for a
no less
forceful sense
that the
sounds one
hears are
unrelated to
the
electricity
fueling these
events. Not
only do the
components
appear to
exist
independent of
the
soundstage,
they likewise
appear to have
nothing to do
with the wall
outlets to
which they're
connected.
When an
audiophile
says he's
closer to the
music, he
often means
that he's hit
upon those
euphonious
effects he
holds as an
ideal. Thus my
discomfort
with this
phraseology.
Euphony, the
great
homogenizer,
is inimical to
accurate
portrayals of
sound in the
can. In this
regard, it
delights me to
report that a
great many of
the CDs on my
shelves sound
better than I
earlier
thought, and
no few, alas
but no
surprise,
worse. Given a
good source,
harmonic
complexities
-- call it
whole-grain
rectitude --
are closer
than not to
those of live,
unamplified
sound. One is
particularly
aware of
distinctions
among
productions.
But placing
the emphasis
on production
blunts the
very strong
impression
that sounds
now lack that
electronic
glaze one had
adapted to
without quite
realizing it.
The effect's
rather like a
seeing an old
painting
recently
restored to
its original
color and
chiaroscuro.
I've
long harbored
the feeling,
looking at the
tickets of
high-end gear,
that I'm in
bad company.
It's clear
that the
stature of
certain
high-end objets
d'art sonique owes
in good part
to
eye-crossing
pricetags, as
an especially
vacuous
parallel to a
celebrity
culture in
which one
achieves fame
for reasons
having little
to do with
genius,
talent, or
even simple
ability. Can
there possibly
be anything
about the
workmanship or
materials in a
$6,000 phono
cartridge or
$15,000
speaker cables
that justify
these numbers?
At a half-yard
under $20k the
pair, yes,
yubetcha, the
Levinson No.
33H is wildly
expensive. But
knowing what
it does, I
cannot bring
myself to call
it a luxury.
Remove two
machine
screws, slide
back the
vented roof
flanked by the
world's most
gorgeously
extruded heat
sinks, and
you're gazing
at a
voltage-gain-stage
board of
unusual
beauty. I've
been to
Madrigal's
Middletown, CT
plant and have
seen these
Levinson
devices spread
out in pieces.
The
promotional
pamphlet
Madrigal
provides in no
way
cosmeticizes
the amp's
interior. They
are, believe
me, that
well made and,
from what I'm
hearing, that
well
conceived.
What a
pleasure to
share one's
space with
these
needle-threading
brutes.
Something
approaching a
technical
note: The 33H
mono power
amplifier is
rated at half
the output of
my now
departed 333's
300 watts per
channel into
eight ohms.
Before I
acquired the
333, I'd been
using a Crown
Macro
Reference
power amp, its
steady-state
output into
eight ohms a
whacking 760
watts. An
amp's weight
relative to
output seems a
meaningless
guide. The
controversial
Crown -- here
disparaged,
there admired
-- weighs
about 80
pounds, the
Levinson 333,
about 150
pounds. As an
earnest of
can-do slam,
the
200-pound-each
33H's declared
output of 150
watts of
continuous rms
power into
eight ohms
("measured
from 20Hz-20kH
with less than
0.5% THD,"
as most likely
a conservative
rating)
doubles as the
impedance it
addresses
halves,
concluding at
an astonishing
1200 watts of
continuous
output, house
current
permitting,
into one ohm!
The amp's
power-supply
tower
enclosing a
huge and
boulder-heavy
3.417kVA
toroidal
transformer
occupies the
core of a
vertical
structure 18½
inches high by
11inches wide
by 23 inches
deep. With its
matte-silver
edifice
flanked by the
heat-sinks'
vertical black
rails, the 33H
is strikingly
handsome. More
to the point,
form follows
function. Much
like the
hot-water
radiators they
somewhat
resemble, the
rails disperse
considerable
warmth. Look
at it this
way: if you
can afford
these lovlies,
you can
probably
handle the
drubbing
they're bound
to give your
utility bill.
Madrigal
recommends
leaving the
33H in
stand-by, in
which state
each side
consumes about
200 watts of
power.
Impressive?
How about at
idle 500-plus
watts each!
One pays for
his pleasures.
As
the very model
of an
exemplary
city-dweller,
one profits
from
electrical-outlet
isolation.
Among the
engineering
claims made on
the amp's
behalf, I'm
especially
cheered by the
"special
power
amplifier-within-the-power-amplifier"
dedicated to
mains
regeneration:
"In
effect, [the
33H derives
its] own AC
power,
creating an
ideal source
for the
critical
voltage gain
and driver
stages ....
portions of
the positive
and negative
DC voltages in
the main power
supply are
siphoned off
and used to
drive a
special
oscillator
that generates
a pure 60 Hz
sine wave
...," as,
I believe, a
feature unique
to power
amplifiers. I
won't trouble
to summarize
the remainder
of what, for
me, yields
elation. Write
Madrigal for
the Levinson
33 / 33H
pamphlet. So
far as I can
determine, it
states its
case in
uninflated
terms.
Clement’s
Comment’s
I've
gone over to
Silverton's on
a few
occasions and
can say his
system always
sounded clean,
with tons of
detail, gobs
of openness
(with focus),
and not too
untidy in the
bass either,
but somehow
the Levinson
electronics he
loves so much
have left me
wanting. (Call
me a
recovering
tubeaholic) At
the time the
Levinson No.
333 stereo amp
handled the
music’s
business. I
wondered aloud
why this was
so, offered
advice on what
to do, of
course to no
avail. Letting
things be is
what Mike’s
about.
Besides, he
knows his
music, is a
hell of a
cook, and
likes the
sound of his
system just
fine, thank
you very much,
good bye. We
apparently
don't have the
same tastes. I
left it at
that, he
resumed his
work for his
webzine La
Folia, and I
began work on StereoTimes.
When Mike told
me by e-mail
that the
mighty 33H’s
had arrived,
my reply was
something
like,
"Call me
when they
break
in." A
few weeks
passed before
everything
settled down
at the mag and
I was free to
do some
listening. I
called my
crew,
"The
Brass
Ear"
Brassington
and "Left
Channel"
Lanese, to
accompany me
to Mike's to
critique these
mighty beasts.
(Everyone
should have a
crew like this
-- they’re
two of the
most
experienced
ears out
there, no
exceptions.)
We
arrived at
Mike’s place
as planned, 5
PM Sunday. I
smelled the
coffee Mike
makes whenever
I visit it all
the way down
at the first
floor. We were
in for a
treat. We
hugged in the
customarily
manly,
audiophile
manner, made
small talk,
discussed the
new mag ...
then we
noticed the
amps!
"How'd
you get them
up the
stairs?"
Was the first
thing
"Left
Channel"
asked. The
"Brass
Ear"
added in his
normal
fashion,
"It
shouldn’t
matter how he
got them up
the stairs.
Just be glad
you weren’t
here to help
when they
arrived!"
Then began the
business of
listening.
"I
can tell you
right now this
system is up
there with the
best of the
best,"
the
"Brass
Ear"
observed in no
less than
twenty seconds
of the first
disc we
played. I said
nothing at
first but in
less than a
half-hour
remarked the
serious
improvements I
heard overall
and especially
in the bass:
not just
tighter,
cleaner, and
more robust
but more
transparent --
unlike any I’ve
heard. We all
were somewhat
taken aback by
the extremely
clear window,
the sheer
expression of
musicality
produced by
these amps
strapped to a
pair of WATT /
Puppy V’s
with nary a
hint of
harshness. The
differences I
recall between
the 333’s
and the 33H’s
are not minor.
What’s more
amazing is the
fact that the
333's power
rating is
twice that of
the 150 watt
(into 8 ohms)
33H’s.
Without
knowing the
rating, there’d
be no way on
earth you
could ever
convince me I
was listening
to a less
powerful
amplifier. To
these ears, it
simply wasn’t
the case. The
"Brass
Ear"
rated the
system at the
top of the
heap in twenty
seconds.
"Left
Channel"
too thought
the system
much better
than he
expected it to
be given
Mike's quite
large loft.
But he too is
convinced
these amps are
a
revolutionary
design
concept.
Hopefully one
day Madrigal
will build
their less
expensive
designs with
the
technologies
employed in
the 33H’s.
Remembering
the 333’s
performance, I
just couldn’t
believe the
differences
one amp
changeover
wrought. That
said, the
price of
admission is
steep. That
this level of
sound quality
actually
exists makes
the journey to
audio nirvana
all the more
refreshing.
