Olufemi Sonuga, chief designer for Dynamic Design
cables, made the point during a telephone
conversation that his designs are conceived of and
intended to be used as a complete package. I find
this attitude totally understandable—I would feel
precisely the same way were I a cable designer.
Certainly changing one or two cables is going to
make an audible difference—indeed many reviews and
home trials are carried out in this fashion—but
ultimately it is not going to let you hear what the
cable system is capable of. And that, of course, is
precisely what the designer wants you to hear. The
word “synergy” springs to mind, a word that if not
vexed, perhaps ought to be.
On the other hand, there is an impracticable side to
the expectation of auditioning a complete cable
system. Not all that many of us have eight or ten
thousand dollars in mad money just lying around in
order purchase a complete Dynamic Design cable
package (even though Dynamic Design offers a 30 day
trial period). Many of us would prefer a taster, as
it were, to get an idea what a cable series “sounds
like.” Some of us have to start small, a pair of
interconnects here, a power cord there. In other
words, of necessity we evaluate cables as a less
than complete package. This is probably more common
than the other way 'round. That is my situation too.
It is not the designer's ideal, but it is realistic
and, I trust, worthwhile.
For logistic and safety reasons I am unable to
include the Dynamic Design loudspeaker cables in
this review. (I get away with running my own
loudspeaker cable across the living room floor under
a rug because I use Nordost Flatline Gold, but
thicker cables pose a potential tripping hazard, as
well as an endurance test for the cables. And a room
rearrangement to accommodate thicker cables is
impractical and acoustically undesirable.) So, I
have installed everything besides loudspeaker
cables, the MK2-XLR digital cable, type SE-XLR
interconnect cables, two Lotus MK2 15A AC cords and
one Spirit MK2 digital AC cord. Price-wise this set
of wires is a few hundreds more costly than my
current reference cables, not a big difference in
cost. In any case, at this price point we're playing
with the big boys (though by no means have we
plumbed the depths of audiophile debt). All
connectors are made by Furutech. The XLR cables are
finished with what appear to be models FP601/602
which feature Teflon insulation, black-painted brass
shells, gold plated phosphor-bronze pins, and
cryogenic treatment.
Those of you familiar with my reviews will be aware
that I devote a lot of space to technical matters. I
am very interested in the theory, materials and
experimentation that went into a final design. When
I contacted him for detailed information about these
matters, Mr Sonuga wrote that, “We at Dynamic
Design believe that purchase decisions should be
made based on careful consideration of a designer's
design philosophy and listening tests in one's own
system, not on generalizations, which is all that
can be accomplished with detailed material lists
anyway.” I don't fully agree with this
conclusion. While detailed material and construction
information may be nonessential to a purchase
decision, such information is interesting in itself.
To me in any case. True enough, in deciding what to
buy, one can easily get lost in technical matters,
matters which may be irrelevant to the vital issue
of how it sounds and how much musical enjoyment it
provides. I remember encountering a similar attitude
many years ago when I questioned Mark Levinson about
an early Red Rose amplifier design: in that
case too my curiosity was destined to not be
satisfied.
The Dynamic Design site provides a number of PDFs
summarizing aspects of their design philosophy and
execution which center around shielding, bandwidth
and dielectric materials. There is, alas, no white
paper consolidating and discussing such matters in
detail. But there are a congruity of factors among
their various cables, whether intended to carry
low-level AC (audio signals), low-level digital data
(S/PDIF signals), or high-level AC (power). Once
upon a time we may have conceived of power source
and power cables as performing independently of
audio signals, but upon closer examination the same
characteristics desirable in a signal cable are also
generally desirable in a power cable. If power cable
shielding is inadequate, no matter how well designed
the power supply, noise can end up riding on the DC
and it will modulate the audio signal. As well,
artifacts of electromagnetic noise, even SHF noise,
can generate frequencies that show up in the audible
range. If a power cable dielectric performs poorly
it can have an audible effect on instantaneous
changes of current flow. Because isolation between
power and audio is never absolute, the audio signal
in effect modulates current draw, which in turn can
effect the linearity of amplification and switching
devices further down the line.
What about insulation? Insulation is a necessary
evil—you can't make a practical cable without it,
but it inevitably distorts the original signal
waveform. Except a vacuum, of course, which is a
perfect insulator with a dielectric constant of
1.0—there can be no distortion due to the
capacitance effects of a dielectric. On the other
hand, every material is imperfect in this
regard and has a dielectric constant >1.0.
Dielectric constant is an relative indicator of an
insulator's capacity to take and hold a charge, to
act like a capacitor. Dielectric constants greater
than 1.0 entail a theoretical two-fold source of
distortion: the charge cycle can distort the
amplitude of the waveform of the original signal,
and the discharge cycle can produce audible time
smear effects.
“The irony about dielectrics,” Dynamic Design
states in a technical note, “is that, at times,
the lossiest ones produce distortions that are very
enjoyable to listen to.” If you recall the tubes
versus transistor debates of yesteryear, tubes were
said to have even-order harmonic distortions which
were regarded as euphonic, i.e., agreeable to the
ear. It's refreshing that this manufacturer notes
that euphony is not the same thing as accuracy.
Different dielectric materials can slow energy
propagation in a conductor by different factors,
usually expressed as a percentage of the speed of
light. In other words, they can add time smear.
Dynamic Design states that the expense of designing
and implementing cutting-edge dielectrics to
minimize time smear accounts for a good part of the
cost of their cables. I'd sure like to know more
about the materials they do use!
Mozart:
Piano Concertos No. 20, 21, Géza Anda,
pianist/conductor, Vienna Symphony Orchestra
(RCA 60484-2-RV). There are some among the ranks of
cognoscenti and would-be cognoscenti who feel that
Géza Anda's interpretation of Mozart's piano
concertos is unsurpassed. I don't know about
that—Clara Haskil springs to mind—but certainly
there is a sense of a very special affinity between
composer and performer/conductor. Rereading Maynard
Solomon's biography Mozart: A Life while
listening to his music has been a profound and
powerful experience. Perhaps all art partakes of the
mysterious and miraculous, but Mozart's art is in a
league of its own. This is the purest music ever
written. And the two concertos on this CD are among
his supreme creations, as well as among his most
universally loved. The Dynamic Design cables are
immensely satisfying in their presentation of this
music, very neutral, with an amazing amount of
detailed ambient retrieval. Indeed, I have rarely
heard such a convincing image and soundstage. The
opening strings in the Allegro of Concerto No. 20
are simply beautiful, naturally and effortlessly
arrayed across the stage with the clear sense of
depth and physicality. As well the opening notes of
the Andante are almost vanishingly delicate yet
harmonically and dynamically rich. Altogether a
lovely presentation.
Michael
Franks: The Art of Tea (Reprise Records 2230-2).
I first heard Michael Franks on a Los Angeles jazz
station, at a more laid-back and optimistic period
of our cultural history. This is one of those
recordings that always sounds good, a well-recorded
small band, electric guitar, sax, drums, electric
keyboard, Mr Franks of course, precise, stable
soundstage and image, a lot of that 'in the room'
feeling. I've heard this CD through the numerous
changes in my stereo, but I've never heard anything
quite like this, quite this present, this pure, this
spacious. And with that strong impression of tonal
neutrality. There is a relaxed quality to the
sound—like putting on a comfortable shirt—an
indefinable something washing over the senses like a
gentle wave, a lucid sense of reality. I've simply
never enjoyed this album more, or felt more
excitement in it's presentation.
Nojima
Plays Revel (Reference Recordings RR-35CD). This
recording, which I've used in one or two other
reviews, is unique in that I was told details of the
studio setup by the engineer himself, Keith O.
Johnson. With the Dynamic Design cables there is a
limpid purity to the sound, a clarity and
articulation that are utterly captivating. Not only
is the position of the piano correct and precise,
but there is a flood of ambient and mechanical
detail. Nojima's breathtaking and nuanced precision,
Ravel's magical and lush evocations, have never
sounded quite this good. One of the pieces on this
CD, Gaspard de la Nuit, is based on a set of
poems by Aloysius Bertrand and it would take a
fellow poet to do verbal justice to the music. I
think no composer, not even Debussy, wrote so
intimately and with such emotional precision for the
pianoforte. The richness, dynamics and rhythmic pace
presented by the Dynamic Design cables is quite
wonderful.
Mozart:
K.271 & K.503, Alfred Brendel, piano, Sir Charles
Mackerras conducting the Scottish Chamber Orchestra
(Philips 5188425). Alfred Brendel has called
K.271 “one of the wonders of the world...Mozart's
first great masterpiece.” I would not usually twice
include a particular composer in a review, but until
a couple of weeks ago I had never heard K.271
(called the Jeunehomme). In those two weeks I
must have played it fifty times. I can't get enough
of it. One of the wonders of the world indeed.
Brendel's playing is punctilious and fleet, noble,
unhurried like a silken landscape. We are clearly in
the presence of a particularly devoted and skillful
interpreter of this work, which was composed when
Mozart was 22. It is very nicely engineered
recording, and through the Dynamic Design cables
there is a wonderful dimensionality and spaciousness
to the sound. The venue is very live and exciting. I
don't know that I've heard a more realistic
presentation of a piano and orchestra.
Some very fine cables, digital, interconnect and
power, have cycled through my stereo over the years
and, frankly, I would be hard pressed to say cable X
is fabulous but cable Y is just so-so. Maybe I've
just been very lucky, but in my opinion all these
cables have been carefully thought out and
constructed in order to implement and fulfill a
particular design philosophy. All of them have
sounded good relative to one another, albeit with
sometimes subtle and sometimes more obvious
differences. In this rather brief review I have
pointed out a number of salient characteristics of
this partial set of Dynamic Design cables. What I
must reiterate is perhaps the most important thing
an audiophile can say about any component: the sheer
musical enjoyment it provides. In the months they
have been in the stereo I have been partaking of an
auditory feast. Although I am a little disappointed
not to have learned more about the materials and
construction of Dynamic Design cables, I have found
them to be a convincing source of musical pleasure
and among the very best I've heard. For anyone in
the cable market, I unhesitatingly urge an audition
of these beauties from Dynamic Design.
