January 2007 |

I reviewed the more modest CD 120 Linear from
Opera Audio by Consonance for The Stereotimes
a little while ago and was so impressed with
it, particularly at its price point ($995.00),
that I simply had to ask USA Opera Audio
distributor Stephen Monte of ‘Quest for Sound’
for a sample of the ‘high-priced spread.’
Plus—I didn’t feel that the one pair of white
gloves that came with my CD 120 was quite
enough for my needs. A fresh pair was
definitely in order.
The CD 120 Linear CD player I reviewed for ST
employs a Kusonoki-type non-oversampling DAC
and I surmised that the blame for its natural,
un-hyped sound-- one competitive with many a
more expensive player (including my
twice-as-pricey reference Lector), might be
laid squarely at the feet of this filterless
DAC. As with the 120 Linear, the 2.2’s
‘Linear’ designation signifies that this unit
too employs a non-OS DAC. However, by way of
justifying the thousand dollar jump in price,
in addition to a much more solid and elaborate
build, this player has yet another goody up
its partly wooden sleeve; namely a triode
output stage utilizing the vaunted C6H30
‘super tube.’ The 6H30 is the very same ‘super
tube’ used by some of the high-end BAT
products in which, I understand, scores
big-time in terms of dynamics and detail over
units using the ‘less super’ equivalent.
The same chunky ‘aluminum brick’ remote you
get with the 120 Linear also comes standard
with the 2.2 and you still get to choose via a
button on it from two different digital
sampling rates—44.1kHz or 88.2 kHz. Regarding
the two sampling rates, while I enjoyed
testing the ‘goldenness’ of my ears by
periodically swapping between them, and while
you may clearly prefer one or the other, I
ultimately concluded there was a pretty slight
sonic difference between the two, with perhaps
the former sounding a bit more ‘rough and
ready’ and the latter a touch more smooth or
‘refined.’ Though the differences were
relatively small, I did appreciate the extra
measure of control over my sound this choice
afforded me. Stephen Monte of Consonance and
‘Quest for Sound’ tells me opinions vary even
among company employees/engineers as to which
is the ‘better’ rate, so don’t feel too bad
about it if you can’t decide on the ‘better’
rate yourself!
So let’s see—a non-OS DAC and a ‘super’ tubed
triode output stage, user selectable sampling
rates, plus another pair of crisp white
official Team Consonance gloves? Whew Stephen,
you had me at ‘hello!’
Sporting
Hardwood
Including the cost of the white gloves, the
Reference 2.2 Linear retails for 1995.00 and
holds the office of ‘vice-president’ in
Consonance’s digital hierarchy, sitting at the
right hand of the Consonance Droplet 5.0, a
curvaceous top-loading player with a polished
hardwood casing cleverly styled to evoke the
aesthetic of a drop of water. This player too
employs tubes, though is (curiously?) fitted
with a more audio-standard 24-bit,
over-sampling DAC in the engine room.
Aesthetically, the Ref 2.2 Linear has in
common with that sultrily styled player a
finished plank of hardwood planed to a gentle
arc, and seated regally atop its otherwise
traditional silver box casement. A bit of
artistic one-upmanship as compared to the
humble CD 120 Linear, this sculptural addition
serves both to soften the otherwise
traditional line a bit, (without going over
the top into ‘chinciness’), while at the same
time shoring up and/or preventing the
otherwise ordinary aluminum casing from
ringing or vibrating to some degree in
‘consonance’ with your music.
The player sports two large polished chromed
knobs on its front, one on either side of the
thick silver faceplate. The one on the right
allows you to tell your elegantly styled
player how to please you-- play/pause etc.,
and the other serves the dual function of
power on/off and opening or closing the rather
sturdy drawer. Interestingly, you do not turn
these knobs (I spent the first five minutes
with the player dumbstruck as to why it
wouldn’t obey its new master). No sir—that
would be too pedestrian. Rather, you nudge
(and that is the best word) them toward the
North, South, East or West depending on what
you’d like you 2.2 to do. She quickly gets the
hint and track access time is mercifully
short. Moreover, the drawer opens and closes
with a reassuring solidity, unlike the CD 120
Linear, with whose drawer mechanism I had some
difficulty.
The
Sound of ‘Super’ Tubed Filterlessness
Fortunately, upon first hooking up the 2.2 I
still had the CD 120 Linear in-house. For once
I didn’t have to rely on audio memory, which,
as many of you can attest to, isn’t terribly
accurate for terribly long! Had I not been
happily listening to the 120 Linear just a few
short hours prior, I wonder if I would have
been quite as dumbstruck as I was by the
relatively striking sonic differences between
them; differences which were quite obvious
initially, seemed to run counter to ‘audio
intuition,’ and which were readily audible
despite periodic changes in ancillary
equipment. Firstly, the 2.2 Linear was somehow
‘faster’ sounding than the 120.
Every
single CD I played, from the Philips three CD
set of Mozart’s String Quintets
[Philips 422511-2], to my girlfriend’s fave
band ‘The Fray’ seemed to have been, to borrow
a phrase that did NOT originate from Harry
Pearson’s pen, ‘kicked up a notch.’ No need to
cite specifics here I feel, as this was an
across the board phenomenon and was
immediately apparent on head-to-head
comparison with both my tubed Lector CDP 0.6T
and the 120 Linear.
By way of corroboration, my good audiophile
buddy and fellow psychiatry resident David
Street borrowed the 2.2 Linear and noted
precisely the same effect via his Gallo Ref
3’s. He too listened to the unit right after
having heard the 120 Linear for a few
days—itself no slouch in the timing
department—and reported the 2.2 was pacier and
punchier. Of note, changing the sampling rate
did not seem to have any impact on this
particular sonic quality.
In
speaking of the 2.2’s propensity to ‘turbo
charge’ rhythms, I shouldn’t neglect to tell
you that, after having had several Consonance
products in for review, including most
recently their excellent mid-priced M400 tube
mono-blocks, all of them seem similarly gifted
rhythmically. In so stating, I do not mean to
imply they are overly ‘fast’ or ‘twitchy;’
merely that with the Consonance line, you
don’t have to worry that a sprinkling or even
a generous helping of tubes in your gear will
equate to superb tonality at the expense of
taught rhythms. Secondly, as compared with the
CD 120 Linear, a player I liked as well as my
Lector, the 2.2 sounded slightly sunnier and
more forward. The choral singers and soloists
for example on one of my fave oratorios,
Haydn’s The Seasons [HMC901829.30],
seemed to have moved themselves toward me a
few feet. The stage they occupied seemed to
define a broader arc and there was more
separation of the vocal parts.
Indeed there was more detail on offer with the
2.2 Linear in general and this coupled with
its pacey nature resulted in musical
transients (the pop of a drumstick on wood or
the twang of a guitar string) that were
literally(!) startling at times. The rimshots
and percussive sounds punctuating and driving
the infectious Latin rhythms on Bebo &
Cigala’s Lagrimas Negras CD [Bluebird
RCA 55910] now took on a punch and snap that
could almost be taken for live. Cymbals on CDs
such as Emmy Lou Harris’s Wrecking Ball
[Asylum 61854-2] were a bit brighter and more
shimmery; more metallic. As I mentioned above,
the 2.2’s sonic signature—brighter, sunnier,
more forward faster-- ran counter to what my
intuition told me to expect. I reasoned that
the tube employed in the 2.2’s circuitry would
likely sweeten the tonality a smidge,
hamstring the unit’s PraT to some degree and
perhaps even sheer off some detail in the
process. I was wrong on all accounts.
I should say that at times there may have been
a slight thinning of the sonority of tones
from the lower middle registers on down. This
did not seem to result in any curtailment of
bass quantity and perhaps the 2.2’s generally
more forward presentation served to highlight
this a bit. This may also simply have been the
2.2 Linear revealing a given recording for
what it actually was — rather than giving me
the slightly more plumped and pleasant view to
which I may have grown accustomed. In this
vein, the 120 Linear does bear a certain tonal
resemblance to my Lector which itself is a bit
‘bloomy.’ Thus both players might have sounded
‘fatter’ by way of comparison.
News
Flash: Audiophile’s boredom results in
shootout
So how would the three different players in my
possession fare against one another if took
the same track of music and fed it to one
right after the other, making only slight
adjustments to the volume when appropriate?
Glad you asked. Bored and lacking for
vibration damping platforms, one Saturday I
decided to stack the three players directly
atop one another, let them all warm up for an
hour or so, and have a go at a favorite
operatic moment of mine — the Pavarotti/Battle
…Esulti pur la Barbara” duet from ‘L’Elisir
D’Amore [DG 429744-2] — via all three
players in relatively rapid succession.
For the purposes of the following, the 2.2
will serve as the ‘reference’ unit. First up-
the Lector; and in switching to it directly,
it quite obviously sounded warm and
weighty—almost too warm and weighty. The
cellos and basses of the Metropolitan Opera
Symphony took on a definite ‘pluminess,’
though the effect was not really objectionable
— just probably not strictly accurate.
It is important here to note that the treble
on the ProAc Response 1.5’s I use as a
reference has always sounded slightly tipped
up to me and it is entirely possible the 2.2
was simply revealing this to a greater degree
than the Lector. Pace was obviously slower
than with the 2.2 driving and sudden musical
entrances and staccato instrumental or vocal
bursts lost a bit of their dynamism and
startle factor. (There was in fact a track on
the …. conducted ‘The Seasons’ recording on…
that contained, if memory serves, a sudden
cymbal crash that was positively heart
stopping via the 2.2 Linear! Well —recorded
door knocks in operas such as ‘La Nozze Di
Figaro’ were also arrhythmia-inducing). There
seemed to be slightly less overall detail on
offer with the Lector, and the soundstage may
have perhaps been less broad, though it
maintained its dimensions in terms of depth.
On to the CD 120 Linear then. Some of the
Lector’s plumminess was removed and now there
was a touch more pace—though just a hair. This
player portrayed detail to about the same
degree as the Lector and had similar imaging
properties, though I do feel it just edged the
Lector in dynamics.
Essentially therefore, the 120 Linear walked a
line Johnny Cash style between the precision
and speed of the 2.2 and the slightly ‘bloomy’
Lector while having about the same facility
with detail as the latter. In sum then, the
two tubed players are at opposite ends of the
tonality spectrum, with the pure solid state
player sandwiched between.
Of note, several reviewers have commented to
the effect that 2.2 is somewhat on the ‘sunny
side of the street’ as compared with
Consonance’s own much beloved Droplet 5.0
player, causing me to believe that the Lector
players likely have a good deal more in common
with a player like the Droplet—a warmer,
err…wetter sounding player.
Conclusion
There are those who feel the Reference 2.2
Linear excels its baby brother the CD 120
Linear in all areas. Do not count me among
them. Both players (and I am not being paid to
say this- trust me) are absolutely superb
examples of value-for-dollar sonics and style
and I for one could live happily with either.
The two Consonance players bracket my Lector
in terms of price, if not quite in terms of
sonic temperament, with the 120 almost
managing to sound like the twice-as-pricey
Lector minus a touch of mid-bass emphasis
(pleasing though it is!) and with perhaps a
shade more dynamic punch. The 2.2 on the other
hand, steps it up a notch as compared with the
other two players in terms of detail, pace,
macro dynamics and soundstage width. It is
also more solidly built than the 120 Linear
with more luxurious ergonomics.
I think it goes without saying that if
you’re in the market, the 2.2 is a player I
would strongly recommend you consider adding
to your own little music box collection. Then
again, I would also strongly recommend you
consider its little brother, and not just if
you’re less thick in the wallet. The 120 and
the 2.2 make different musical arguments to be
sure, though both speak eloquently.
Along these lines, I would conjecture
that if your system tends toward the warmer,
perhaps slower side of things, the 2.2 Linear
might be just the kick in the glen-plaid pants
you’re in need of. Likewise, if you’re the
proud owner of say, a pair of older Thiele
speakers and a big ol’ Krell amp set up just
so in your imported Italian marble room, the
detail of the 2.2 might be too much of a good
thing.
In other words, the 120 Linear is a bit more
forgiving and probably gets along better with
a broader range of equipment, whereas the 2.2
is more demanding in terms of ancillary
equipment and system synergy, but offers in
return the aforementioned gains in resolving
power, dynamic punch and pace.
I really have to hand it to
Consonance. I have now reviewed two of their
CD players and a review of their jewel-like
M400S monoblocks is forthcoming. I have yet to
hear their components do anything untoward. To
the contrary, all three of these pieces have
given me hours of listening pleasure, sport
tasteful- even artful styling, and don’t cost
the earth. Let’s see—only 50 or so more
delectable Consonance products left to review
and I’m done—Stephen Monte are you
listening??!!
