December 2006 |
The
Nova Physics Group Memory Player has arrived,
and it has changed my opinion of digital
playback in the home, as well as the opinions
of a number of my fellow audiophiles whose
ears I trust implicitly. The Memory Player was
conceived by former Melos Audio designers Mark
Porzilli and George Bischoff—makers of the
gargantuan Nearfield Pipe Dream loudspeaker.
Rod Handley, a wonderful gent whom I met at
the recent Denver Rocky Mountain Audio Fest,
puts the Group in Nova Physics as the third
and final partner.
Since
earning a “Publisher’s Choice Award,”
emails from all over the world have been
arriving, inquiring about the Memory Player's
performance and availability. Each time I
responded with “review forthcoming.” Internet
chat rooms have heated up as the Memory
Player's claimed technical virtues have been
debated. Very seldom has the introduction of a
product generate this much response.
Well, the
“forthcoming review” has arrived, so please
read on.
After the initial introduction of the digital
CD format, it quickly became obvious that CDs
were not providing the promised “perfect sound
forever.” Improvements accrued with our
understanding (and discovery) of the problems
of reproducing audio in digital format. And
the past five years have seen tremendous
growth in the quality of digital playback.
There’s no question that recent players and
converters have been well-received by
audiophiles and press alike.
With the advent of larger hard disc storage
capacity in smaller packages, digital music
servers (as well as the ubiquitous iPod) hit
the scene with staggering results. There are
now music servers costing many thousands of
dollars beginning to surface in the homes of
audiophiles, such as the Squeeze-Box, Olive
and VRS.
In appearance the Nova Physics Group Memory
Player looks nothing more than a one-box PC
with a built-in touch-screen LCD. On/off
buttons on the front panel control power
standby for the main unit, and for the
display. The rear of this transport-only unit
has an XLR output, on/off main power switch, a
BNC connector for an external word clock, and
a standard IEC power connector. A relatively
inexpensive PC laptop comes at an additional
$600 (or you can install the software on your
existing laptop) for remote control. The
Memory Player's operating system is rather
crude compared to mainstream music servers
that have every sort of gizmo available at the
click of a button. There won’t be any
mistaking this unit as the latest offering
from the folks at Microsoft! That said, what
lies behind the Memory Player has nothing to
do with its looks: sheer musical performance
is the genius behind the Memory Player.
“Read-until-Right” is the principle that lies
at the heart of the Nova Physics Group Memory
Player and that enables it to achieve its
stunning sonic effects. When a CD is placed in
the Memory Player, the laser will first read
the disc like any other CD player, but what
distinguishes the Memory Player is what
happens when the laser encounters a hard to
read spot on the disc (and this happens
hundreds or even thousands of times per disc,
either from dirt, scratches, surface
imperfections or eccentricity). A standard CD
player at this point will introduce Error Code
Correction or Error Concealment Correction (ECC)
and Parity Bits. The Memory Player disables ECC and Parity Bits and engages its
Read-Until-Right (RUR) and Dynamic Laser
Positioning (DLP) software. RUR attempts to
retrieve the original information on the disc
by engaging its DLP that repeatedly shifts the
laser angle. Only when the information can’t
be extracted after hundreds of attempts do
Error Code Correction and Parity Bits kick in,
creating as perfect a theoretical facsimile of
the missing information as possible, as in
standard CD players.
The Memory Player’s purported theoretical
inner workings were met with claims to the
contrary. Certain well heeled audio
journalists labeled the Nova Physics Group
white paper so much as hogwash. And based
solely on this document, they said, the Memory
Player could not make an audible difference!
But, interestingly enough, the journalists
making these claims had not heard the Memory
Player. I have.
The one thing on which there is general
agreement is that CD reproduction is far from
perfect sounding. Porzilli and Bischoff, the
Nova Physics Group founders, point to the
extraction mechanism as being more culpable
than the media. And both pondered at length as
to why removing ECC and Parity Bits actually
increased sonic excellence. I highly recommend
reading their latest white paper
here.
Operating the Memory Player is quite
straightforward, though I would hope potential
users possess, at the very least, a
rudimentary understanding of computers. If
you’re reading this review, you're using a
computer, and therefore should have no
problems whatsoever.
Navigating through the LCD screens can be
intimidating and even frustrating at first.
But I had a generally easy time getting the
Memory Player up and running, and I wouldn’t
qualify myself as a computer geek. Savvy
computer experts who want lossless hi-rez
music should rejoice in the Memory Player's
ability to store and playback hundreds songs,
and the user's ability to play them with a few
touches of their fingertips.

When a CD is loaded, it’s read directly onto
the Memory Player’s flash memory stick, which
can hold 2 gigs of data, or up to two CDs, with
an average extraction time between seven and
ten minutes per disc (faster drives are
optionally available). It is during this
initial operation that Read-Until-Right and
Dynamic Laser Positioning come into play. Once
loaded, the data can then be opened in the
Memory folder; the folder can then be dragged
onto the Memory Player’s Playlist. It is from
the Playlist window that the Play, Stop,
Reverse, Forward and Pause buttons are
functional. The Playlist is where users will
spend the majority of their time. Actually
saving your loaded music requires the use of
the Memory Player's internal hard drive,
available in different sizes. Standard is 50
gig (80 CDs), or you can upgrade to a 300 gig
drive (600 CDs). The Icons located on left
side of the screen (photo above) provide easy
access to folders like the hard-drive,
playlist and extraction window.
Burning CDs from the Memory Player is a
feature I found myself using quite a bit
during the review period. Recording CDs
directly from its internal memory stick has
sonic advantages that in many ways proved
how sound the Memory Player performs in theory. What I mean by this is: In the
context of my system, unless you're deeply
familiar with each component, it's very hard
to determine what's doing what. Therefore,
I’ve burned plenty discs from the Memory
Player and had given them to those who
questioned the Memory Player's performance in
light of the mighty Behold electronics and
DALI loudspeakers sharing the same space.
Well, on conventional players they confirmed,
the burned discs were actually superior
sounding to the original. Go figure.
The business of reviewing isn’t always easy.
I’ve lived with many different
players/transports in my audiophile life, the
more memorable performers coming from such
esteemed brands as Electrocompaniet, Esoteric,
Zanden, Gryphon, Reimyo and Wadia. My personal
enjoyment of these machines has been immense,
and each unit had individual strengths that
would inevitably be put to the test whenever a
newer, and potentially superior, component
appeared. This experience has taught me what
to expect from digital in general (and digital
amplification in particular). And I can say
unhesitatingly that the Nova Physics Memory
Player is the most musical and indefatigable
CD player I’ve heard.
The
Memory Player is the only player I’ve ever
owned where the first song heard was
indelibly tattooed onto memory: Star Eyes from
the excellent 1995 trio recording featuring
Roy Hargrove, Christian McBride and Steven
Scott from Parker’s Mood [Polygram
B046ZS]. It is very rare that a component, any
component, leaves an unforgettable impression
on nearly everyone who chances an audition. I
was told by Bischoff that more than a dozen
orders for the Nova Physics Memory Player were
placed after listening sessions here were
concluded. Of these, five were Stereo Times writers Greg Petan, Lew
Lanese, Don Shaulis and Dennis Parham (new to
the team) and of course, yours truly. This is
unprecedented in my experience, particularly
for a product that retails for $10,000! It was
a relief to know I was not the only person
placed under the spell of this hypnotic
machine!
The sonic character of the Memory Player reads
like an oxymoron: buttery soft and voluptuous
where it needs to be, while simultaneously
astonishingly fast and detailed. Euphonically
colored it is not, ruthlessly see-through it
is. Massed strings, no matter what the
transport, have always sounded, well, like
massed strings. Not so with the Memory Player.
It differentiates individual players among
scores of musicians like nothing I’ve heard
previously. Another astounding sonic feature
of the Memory Player is no matter the volume,
size, complexity or musical genre, if the
recording is well made, the sound never
becomes hard and/or glare-ridden.
It is easy to wax poetic on the
virtues of this machine, but harder to explain
why the Memory Player possesses such
attributes. Clearly, though, if removing ECC and
Parity Bits offer these profound
sonic benefits then it should be certainly worth further evaluation and
discussion.
Perhaps
the Memory Player's most salient quality is
its bass performance. Improvements in the
upright bass, whether being plucked on a jazz
set or bowed in a classical performance, were
unmistakable. In a word, clarity, to such a
degree that for the first time I got a sense
of the fingering method, and more importantly,
the complexity of, for example, bassist Gary
Peacock's playing on the legendary six-disc
box set Keith Jarrett at the Blue Note.
This set possesses rare qualities, being one
of the most excitingly hip and happening jazz
trios in a “live” recording by perhaps the
best recording engineer in the business, Jan
Erik Kongshaug. I have long considered this
set one the most glorious in my collection
(Downbeat gave it “Recording of the Year” in
’96). On “Don’t Ever Leave Me,” Peacock’s
performance is unforgettable. Drummer Jack
DeJohnette’s cymbal accents highlight and add
greater illustration and beauty to this
melancholy performance. If ever there was a
single product to come along and endow the
listener with the feeling, mood, and sentiment
that exists in this piece, it's the Memory
Player. Its ability to renew the very color,
nuance and fundamental shadings of this
masterful trio’s recording is simply
extraordinary.
The Memory Player's spatial acuity is also
surprising. It can sort out the most
complicated passages in recordings such as
Reference Recordings' Requiem and Five
Anthems [RR 57 HDCD] and Testament. Massed voices
were transformed into multi-tiered layers with
incredibly precise and articulate diction and
intonation. Ditto even small jazz trios, where
microphone placement gives a precise sense of
where performers were standing. The Memory
Player creates a sonic landscape that is
wider, deeper and much more lifelike. And what
the Memory Player does for great male
vocalists from yesteryear is mind-boggling.
Joe Williams, Andy Bey, Johnny Hartman, Lou
Rawls and Mark Murphy, sing in way that got my
appreciation soaring higher the more I
listened. Ditto female legends Ella, Sarah,
Shirley Horn, Betty Carter and the underrated Morgana King.
Comparisons…
Listening to music from different transports
ranging from Behold Electronics CD768 to the
highly revered Wadia 270 SE proved just how
much things had changed on the digital front.
While the Behold and Wadia sounded delightful,
there was sonic shift to the sound that
inevitably proved something missing. The bass
via these conventional players has significant
fuzziness in the 70 to 100 Hz range, a
phenomenon I would have had problems accepting
had I not personally compared them side by
side. Comparisons such as this ALWAYS reveal
the phenomenon of removal first, exposure
second.
Once exposed, it is more apparent what has
happened to the music. On the Memory Player
everything sounds clearer, more tonally and
spatially correct in a way that is invariably
more mesmerizing. The true-to-life perspective
becomes increasingly more apparent. On the
Wadia or Behold you get musically taken away,
but to a lesser degree than on the Memory
Player.
Finally, there’s a certain quality that exists
in both the Wadia and Behold players that
simply vanishes in the Memory Player. The
closest I can come to describing this quality
would be the analogy of turning up the
contrast on your television. This higher
contrast in the Wadia or Behold don't make
them sound brighter necessarily, they simply
don’t provide the full authenticity or the
rich and textured tints of real instruments to
the degree the Memory Player can.
Taking
this Show on the Road…
One of the first things I did when I got the
Memory Player was call reviewers living around
here, as well as audiophile friends who are
also serious jazz musicians. Each stated
pretty much the same thing using different
words after extended auditioning: The best
they'd heard! You can read their testimonials
on the Nova Physics Group website
here.
I next took the Memory Player show on the
road. First up was a major audiophile
recording studio in New York City to see how
it would compare against their professional
house machines. Believe it or not, the
president of this label, a friend and an
audiophile, was quite excited. Resting side by
side next to a high-end transport from Theta
Digital using a very expensive digital to
analogue converter, the Memory Player clearly
outperformed studio house masters! All I
recall he and his engineers saying, as I was
packing up the Memory Player and heading for
the nearest exit, was “how can this be?”

Next up was a fully loaded Memory Player with
its own 32-bit tube DAC and internal volume
control going up against the $42,000 digital
stack from Zanden Audio (photo above). This fully loaded
Memory Player belonged to another writer who
had invited me over to hear his rig.
It was
more coincidental than planned that at the
same time, another audiophile with serious
industry credentials wanted to hear this unit. In addition to having a front-end consisting
of the Zanden transport and DAC, he also had
the new German ASR amplifiers and the BIG NOLA
reference loudspeakers. I had a good idea of
what to expect, having owned a Zanden myself.
Yes, to answer your question, I was a tad
nervous. Regardless of how good a component
is, it is very hard to imagine getting
identical results in different locations.
Once we got the two side by side, it only took
four songs give or take, to prove that as good as the
Zanden combo was (and I must reiterate it’s a
world class product I could happily live
with), it could not reproduce the music in the
way the Memory Player could.
Again, it goes back to what I can only
describe as contrast and tint. Wonderful but
unfamiliar music loaded on the Memory Player,
and played back through the Zanden combo,
showed why this music lover chose these
products to begin with. The music was
resoundingly open, musical and palpable with
an incredible low-end presence. Surprisingly,
the Memory Player opened up the soundstage
both laterally as well as front to back,
showing a greater sense of low-end wallop and
detail up and down the frequency spectrum.
But, in the end it was the authenticity of the
instruments that won us all over. At the end
of this comparison, the Zanden owner, after a
very long pause and without a single utterance
from myself or the Memory Player owner said,
“This is an marvelous product, Absolutely
remarkable.” It was obvious he didn't care
about the financial value of components, only
the musical value. (Far too often I see
property and prestige take precedence over
sonic performance. Many audiophiles purchase
high priced systems reviewed over and over in
the audio press because they only want to be
associated with gear that’s respected. This of
course, is total BS. It was refreshing to
witness performance chosen over prestige. Keep
in mind, I was the first reviewer in the US
to own the Zanden electronics and for all the
glorious things the DAC does, it couldn’t
float my boat dynamically. I’m told that its
$28k transport fixed that. Well, at that price
it better had.)
Conclusion...
In summary, if I were forced to answer
the claims of what the removal of ECC and
Parity Bits offer a music lover and potential
purchaser I would have to say; a
super-translucent window into performances
with greater dynamic ease and
three-dimensional depth. Bass loses that wooly
coloration that, I for one never knew was
there, and replaces it with a quality pitch,
definition and clarity that should startle
anyone as fortunate as I was to hear this
product. After hearing the Memory Player in so
many different locales it would be hard to
discount its manufacturers claims. Very hard.
The Nova Physics Group Memory Player
has laid down the proverbial gauntlet with
regard to sonic supremacy in digital playback.
As far as I can ascertain, and through many
exhilarating months of intense listening
sessions, it appears that Porzilli and
Bischoff were right after all. ECC and Parity
Bits may very well be the culprit behind what
ails digital to this very day. With the
onslaught of computer-based music servers
hitting the market, I’m certain it will only
be a matter of time before the Memory Player
will meet its sonic match as the competition
catches up. But in the here and now the Nova
Physics Memory Player stands as the standard
upon which high-end digital playback will be judged.
The performance of the Memory Player has taken
the overall satisfaction of playing back music
on CDs to a place I doubted possible. As I stated
after my first audition…Game Over
