The Clearaudio Champion
Level 2 is the pinnacle
of Clearaudio's Champion
line of turntables.
Owners of the Champion
and the Champion Level 1
can upgrade to it by
simply paying the
difference in retail
price. One can of course
simply purchase the
Level 2 complete. The
Champion series also
includes a list of
options and accessories,
including a new record
weight, their APG
(Accurate Power
Generator) motor power
supply, an edge of LP
record clamp and a
dedicated alignment
protractor.
The Champion Level 2
turntable consists of 2
acrylic plinths
(available in clear or
black) separated by 4
cylindrical metal
isolation feet. The top
plinth holds the
inverted platter bearing
and the heavy and
2.5-inch tall silicon
acrylic platter, along
with the tonearm mount.
The bottom plinth rests
on 3 more of the
cylindrical feet,
terminated in small
spikes. Clearaudio
includes shelf
protection cups in which
the spikes rest. A
swerve in the cut on
both plinths produces a
kind of bay, allowing
placement and adjustment
of the outboard
synchronous motor's
position. Drive to the
platter is via a round
cross section rubber
belt. The motor housing
contains a flying AC
cord lead and power
switch and is contained
in a heavy, metal
cylinder whose isolation
feet rest on still
another heavy, metal
cylinder, also with
compliant feet. The
drive pulley is held to
the motor shaft by 3
plastic screws. Speed
change is manual. The
optional APG allows
toggle-switch speed
change from the APG
unit.
The platter's milky
color contrasts with the
GS acrylic of the
plinths, the entire
turntable presents an
austere, precise and
rather clinical
appearance, somewhat
monumental in presence,
and evoking, in my case,
the visuals of Fritz
Lang's movie
Metropolis. The 79.2
lbs. weight puts the
table into the high mass
design school; there is
no suspension as such.
The Champion is well
packaged in 2 separate
boxes and a complete
tool kit is included
along with a set of
white gloves to keep
from smudging the
acrylic surfaces while
setting up. The
instruction manual could
use a good re-write and
expansion in the detail
of the set-up. I may be
the only US male willing
to admit to reading
instructions before
beginning assembly of
anything and the more
precise and detailed the
instructions, the
happier I am. Clearaudio
offers an optional
alignment gauge at $150
that eases setting
alignment and overhang.
A Souther Clever Clamp
is standard;
Clearaudio's clamp is a
$150 option. Missing was
a strobe disc, making
setting speed (achieved
by slightly rotating the
motor housing and thus
distance of the pulley
from the platter)
slightly ambiguous. I
used a KEB strobe to
check final results.
The Rega-based arms I
used - Clearaudio's RB
300 ST (re-wired with
Clearaudio Sixstream
cable, incorporating the
heavy tonearm counter
weight also used with
the Unify arm, and the
use of stainless steel
in certain areas,) the
Origin Live RB 300 and
Silver 250 - mount by
screwing the arm's
threaded pillar into the
removable acrylic
armboard, self-tapping
the threads in the
pre-cut board hole. The
stock Rega locking nut
is then used to lock the
whole into place. This
is also the method for
adjusting arm height.
Given the difficulty of
this adjustment - loosen
locknut, disconnect
tonearm leads from
preamp, rotate entire
arm 360 degrees until
required arm height is
achieved, taking great
care not to lunch stylus
as it passes over the
spindle and unwinding
the captive arm lead as
you rotate - changing
arm height to tune
VTA/SRA for individual
records is not likely.
It also made comparisons
of the Ringmat to the
stock clamp/bare platter
set-up difficult and
tedious.
The entire open-cylinder
arm mounting platform
can be slightly rotated
by slackening 6
hard-to-access Allen
head bolts under the top
plinth at the bottom of
the arm mount cylinder,
allowing movement of the
entire platform to set
stylus overhang and
tangency. This
adjustment inspired
heights of mechanical
frustration and fury, as
one has to find the
Allen heads blind and in
a narrow space between
the two plinths
prohibiting easy
entrance of fingers. The
reflections in the clear
acrylic also produce
parallax distortions
that make matters even
more of a pain. I would
deeply welcome a change
to this adjusting
arrangement. Simply
moving these bolts to
the top of the arm
platform would ease this
crucial adjustment and
facilitate arm board/arm
swaps. The tonearm leads
are not attached to the
turntable chassis.
I installed the
Clearaudio RB 300ST, and
placed the Champion 2 on
the top shelf of my wood
shelf/steel column rack.
The top shelf of this
rack is rated for 350
lbs. and the entire rack
rests on a concrete
floor. Initial sonic
impressions with a
variety of cartridges
were of a rather laid
back, slightly smeared
presentation, though
with smooth and very
even tonal balance.
Detail was subtly
submerged and blurred
quite a bit and was
immersed in the sonic
presentation, being
neither obvious nor
upfront. Dynamics and
phrasing were subdued
and the whole
presentation, while
pleasant enough and
non-aggressive, had a
kind of background
listening, Muzak-type,
fog-enshrouded effect. I
experimented with
various LP placements:
neat on the platter,
with the included
Souther Clever Clamp,
the optional $150
Clearaudio Clamp (really
a record weight as it
makes no attempt to
clamp the LP to the
platter), and the
Ringmat Record Support
System. The optional
clamp proved well
matched to the table and
unlike many clamps that
attempt to mate the LP
with the mass of the
platter, did not produce
slow and turgid rhythms
or other anomalies.
The Champion does not
have a suspension as
such and depends on high
mass, internal
self-damping, and
mechanical decoupling to
achieve isolation from
internally-generated and
external environmental
vibrational
interference. The sonic
results had me
suspecting that the
blurring, smearing and
overall foggy and
musically un-involving
results were the effect
of inadequate isolation.
Banging on the shelf on
which the Champion II
rested produced no
acoustic breakthrough,
but I've found this test
pointless, as many
tables unaffected by it
still have problems
dealing with subsonic
interference.
I placed the turntable
on Aurios PRO Media
Isolation Bearings with
Optional Top Ball (first
placing the table on a
separate board to allow
the tripod Aurios to
work) and was greeted by
an immediate
transmogrification of
the blurred sound into
something commensurate
in quality with the
price of the turntable.
Much of the blurring
went away: there were
now identifiable
transient starts and
stops to notes, the
space and time
between notes
finally emerged from the
murk, and timbre and
musical aspects of
performance became
clearer and better
articulated. It started
making musical sense.
Placing the table on the
Ganymede VCS had similar
results; the 80 lb.
weight of the Champion
exceeded the weight
tolerance of my Seismic
Sinks, however, and thus
precluded their use.
All was not perfect
however, nor
satisfactory: there was
still some smearing
apparent. About this
time I received the new
AC motor replacement for
the original motor with
which my review table
had come. This new
motor, sourced from an
unnamed Northern
European manufacturer,
significantly tidied up
the presentation by
removing more of the
haze and blurring,
locating images in the
sound field better,
increasing focus, and
improving the urge and
general movement of the
musical line.
I swapped the 300 ST arm
for the OL RB300 and
heard an immediate
improvement in musical
articulation and drive.
The Origin Live arm,
however, responds best
when only just snugged
up by the arm nut and
the Champion's threaded
arm board arrangement
compromised the OL's
bass articulation,
control and drive,
nullifying the crispness
of attack and control of
starts and stops of bass
notes.
Finally, I mounted the
Origin Live Silver 250
along with the Ortofon
Jubilee moving coil
cartridge and the
Champion finally began
to come alive and create
music. Resting the
table's spikes into
A.R.T. Q-Dampers instead
of the supplied cups
removed another layer of
haze and fog. At this
point, I finally began
to get some musical
satisfaction from the
Champion 2.
The addition of
Clearaudio's $1800
Accurate Power
Generator, or APG,
offered an enormous
increase in performance,
so much so that I would
consider it a necessity
rather than an option.
The addition of the APG,
which outputs a pure 60
Hz frequency to the AC
motor, improved the
sense of drive and
articulation of phrasing
and musical lines from
the merely good to very
good. Transients were
far less slurred: good
motor control not only
articulates the sounds,
it also clarifies the
silence between the
sounds. Its effect on my
basic AC motored
AR/Merrill and Linn
Sondek Nirvana was
equally impressive,
proof again that one
cannot rely on the 60 Hz
AC coming from one's
wall to adequately lock
AC synchronous motors to
their correct speed. I
found the APG to be
absolutely essential to
the Champion's musical
performance.
There has been a vogue
for unipivot arms in
recent years in the
high-end audiophile set.
The Graham, VPI, and
Naim Aro unipivot arms
have become the darlings
of high-end reviewers
and de rigueur high-end
recommendations.
Clearaudio's Unify, at
$800 when purchased with
a Clearaudio table, is
the least expensive
unipivot on the market.
It incorporates a carbon
fiber arm wand,
upward-facing pivot,
adjustable VTA and
azimuth, and thread and
bob-weight antiskate.
The pivot is undamped.
An undamped cueing lever
and armrest are
included, the lack of
damping aiding a linear
and more controllable
descent of the arm while
cueing a record.
I must admit a lack of
enthusiasm for unipivot
arms. Past experiences
with the older unipivot
arms, e.g., the Mayware
Formula 4, Keith Monks,
Magnepan and the
Connoisseur SAU 4 and
with more contemporary
Grahams, Immedias, and
VPI's have never really
raised a fire in my
musical consciousness.
To be blunt, unipivot
arms are a pain in the
ass to both set up and
use. The Unify continues
this unipivot tradition.
The problem with
unipivots is that they
are inherently unstable
and would like nothing
better than to fall off
their single pivot
bearing. A comparison is
often made to a high
wire performer who would
immediately fall if not
for his long balancing
pole which produces the
necessary balancing by
placing the center of
gravity below his feet.
The cartridge, tonearm
and its counterweight
are roughly analogous to
the balancing pole and
balancing the whole mass
depends on careful
adjustment to avoid
introducing distortion
of stylus azimuth (a
slight tilt to either
side when viewing the
stylus in the groove
from the front), which
can range in effect from
the quite small
(compromising stereo
separation,) to large
side-to-side wobbles
which raise serious
fears as to the safety
of the stylus and the
effect of the stylus
wobbles on the record
grooves. The problem is
that the high wire
artist must be
constantly inching his
feet and re-balancing
the pole to keep from
losing balance, which
the pivot on the arm
cannot do.
Set-up of the Unify was
harrowing and
anxiety-inducing: angel
hair tonearm/cartridge
lead wiring looked
completely intolerant of
mechanical slip-ups,
tracking force
adjustment and overhang
complicated by the Unify
wobbling side-to-side.
Routing the arm wire and
its fastener to the
tonearm base and then on
to the RCA connector box
(an option which allows
one to choose one's own
interconnect) had to be
done just so, as the
wire can foul the
antiskate arm if not
attached properly. This
wire is also very thin
so as not to add
resistance to movement
of the arm as it
laterally tracks the
record. I've always
hated thread and hanging
bob-weight anti-skate
devices and I hate them
even more on the Unify:
the slightest swinging
of the bob-weight
introduces wobble in the
arm. Adjusting azimuth
is wisely achieved by
the slight rotation
possible in the
headshell (an Allen bolt
allows this adjustment
to be then locked-in)
rather than by moving
the center of balance of
the counterweight off to
either side.
Operation of the tonearm
requires learning a new
set of handling
procedures to minimize
the arm wobbling. Once
the stylus is in the
groove, so the unipivot
theory goes, it is quite
stable: the trick is to
get the stylus into the
groove and stabilized.
Clearaudio chose not to
damp the pivot for sonic
reasons, and the
resulting trade-off is
more wobble when the arm
is moved while off the
record. Removing the
tonearm from its armrest
lock begins the wobble,
exacerbated by the
swinging anti-skate bob
weight. Lightly touching
the bob-weight to stop
it swinging after moving
the arm to its cueing
platform helps. The
cueing is undamped and
directly linear so one
can slowly lower the arm
to the record and just
ease off at the end of
the cue, but even with
my best Slow-Hand skills
(compromised because the
height of the platter
eliminates a place to
rest and stabilize one's
cueing hand) there was
still a momentary wobble
after the stylus touched
the record. Waiting for
the arm to stabilize in
the groove evoked deep
sympathy and concern for
what was happening to
the stylus until the
wobble stopped. Cueing
the arm up presented no
difficulties.
It took substantial and
conscious applied
phenomenological
'bracketing' to remove
my reservations about
unipivot arms and to let
the phenomenon speak for
itself (I did, however,
hedge my bets by using
easily replaceable LPs
and was thankful that I
was using Clearaudio's
loaned Sigma Wood rather
than one of my own
cartridges.)
Reservations didn't
translate into
audibility, however: in
audiophile terms the
Unify/Sigma was truly
superb, offering a
balanced, wide and
tautly controlled
bandwidth with an
extremely
neutral-sounding
frequency response,
superb and solid imaging
placement and rendering
of the sound
field/scape, and
top-drawer resolution of
fine detail at the
frequency extremes. The
Unify/Champion/Sigma
sounded very impressive
indeed in the usual
audiophile sorts of
ways. But it was only
very good in allowing
the basics of music to
be communicated.
The tracking of subtle
volume changes in
playing, while not
mechanical and lock
step, was nevertheless
not as fluid as the best
tables, and was somewhat
homogenized and
averaged, failing to
completely track the
differing and subtle
volume levels and the
dynamic gradations of
multiple instruments
playing together.
Consequently musical
punctuation, phrasing
emphasis and arrival,
and the emotional (and
even the intellectual)
meaning of the playing
was obscured enough to
cause a curious lack of
involvement in what was
going on, despite the
spectacular sonics.
Rhythm was also short of
the very best. The
overall effect played
more to cerebral
appreciation, rather
than to the heart, and
while not alienating,
clinical, or chilly in
its results,
nevertheless, resulted
in listening to music
becoming an
intellectual, sonic,
audiophile experience: I
was never moved to
ecstasy, rage, tears,
joy or exaltation. And,
perhaps the worst for
me, there was no direct
insight into the
consciousness of the
performers behind the
otherwise superb sonics.
Admittedly this
limitation was largely
the sonic signature of
the Champion turntable -
it was present in all
its incarnations during
my auditioning - and was
not a contribution of
the Unify/Sigma. Nor was
it a function of the
Clearaudio Sixstream
interconnect running
from the RCA arm-wire
junction box, as this
interconnect proved the
best of a variety of
other interconnects that
I tried.
All in all, I'd have to
view the Champion/Unify
in the context of other
high-end, high mass
audiophile
turntable/unipivot arms
I've spent time with or
sold in the retail
world. Sonically, the
table was excellent with
superb and transparent
rendition of timbre and
precise positioning
within and delineation
of the soundfield, and
was without the usual
plodding rhythmic aspect
that so dims my
enthusiasm for other
high-end high-mass
turntables. Only its
lack of intense musical
communication - stemming
from less than
top-drawer rhythmic
drive and dynamic
articulation - kept me
from shouting "Eureka!"
and giving it the
highest recommendation.
I predict though that
audiophile listeners
with a bent toward
intellect and
sonic-based listening
(and with the motivation
to develop delicate
arm-handling techniques)
will go absolutely ga-ga
over the Champion and
Unify. More so than
ever, a close audition
will be absolutely
necessary to determine
whether its lack of
ultimate musical
communication evokes the
same lack of involvement
that the combination
produced in me.
