As an audiophile, I have been in a
rather enviable position over the past five
years. While digital technology has traveled a
treacherous path towards musical truth, I’ve
been in possession of what was, and still is,
a CD player that represents the best of what
this otherwise perplexing medium has to offer.
As my cohorts have spent their valuable time
desperately seeking just the right transport,
DAC, and digital interconnect combination, not
to mention burning carbs in an effort to sort
out the sonic benefits of the new competing
hi-rez formats, my trusty one box solution has
sailed along with ease. In all fairness, my
Linn CD12 does go for - Que the spit take - a
cool $20k.
So when Jeffery Smith of Silversmith Audio
cable fame suggested I give the Dodson DA-218
DAC a listen, I didn’t exactly move heaven and
earth to make it happen. After a few casual
e-mails between proprietor/designer Mr. Ralph
Dodson and myself, the DA-218 finally found
its way into my system. The previous week, a
whole new tangle of power chords,
interconnects and speaker wire arrived from
Virtual Dynamics, a company you will be
hearing a mouthful about shortly. As well, a
new monster speaker from Krell Industries took
up a position in my system. This amalgam of
new products created a beast of a system that
I would have to spend much time and effort
fine-tuning. After a couple of weeks of
schlepping, tweaking, twisting, tightening,
spiking, plugging and unplugging more times
than I can count, I achieved a modicum of
system synergy that would allow the DA-218 to
do what it does best. In the end, I removed
the big Krells and back in went my Talon
Firebirds. Changing speakers at this point was
just too much change to grasp.

Here are the unique features Ralph has
implemented in the DA-218:
- Cryogenic treatment-
Eliminates crystal boundary formations and
stresses in solder joints throughout the
circuit boards and resistors.
- Cutting edge upsampling and oversampling.
All input signals are upsampled to 96kHz via
an algorithm that produces a s/n ratio of
-117db digital filters oversample to 768kHz
sampling rate and 24-bit word lengths.
- Bybee Quantum
Purifiers remove noise at the incoming AC.
- Extensive use of internal non-magnetic
shielding throughout the chassis, power
supplies and circuits.
- Individual power supplies for analogue and
digital sections
- balanced four layer printed circuit boards
- Custom capacitors made to Dodson’s specs
- 100kHz wideband analog filters
- No-jitter re-clocked signal to the
24-bit/96kHz DAC chips.

Visually, the DA-218 is rather under whelming,
reminding me of an entry-level high-end
component rather than the cutting edge piece
that it is. For nearly $8k, I would beg Ralph
to give the DA-218 a cosmetic overhaul. I
understand that this is a limited production
product, thus raising the price for machining
fancy casework, but if there is something that
could be done, to spruce up the looks I
believe it would draw the attention that it so
richly deserves. Despite its utilitarian
appearance, the interior treatment mentioned
above is truly cutting edge and I am glad to
report that the DA-218 is solidly constructed
and operated without a single glitch. Luckily,
my unit had several hundred hours on it before
it arrived and that is a good thing. According
to Ralph, the DA-218 takes a very long time to
burn in, somewhere between 300 and 500 hours
to maximize. Connections include one set of XLR and RCA analog output jacks. Digital
connections are one RCA, one BNC, one Toslink,
and one XLR. The front panel also has phase,
signal lock and de-emphasis indicators. There
is a button dedicated to each function
including a standby feature, which acts as a
power on/off switch.

My initial impression of the DA-218
was as immediate as it was favorable. The
Model DA-218 has an extremely lively feel,
accentuating rhythmic propulsion on both
small-scale dynamic contrasts as well as “the
broader fundamental rhythm.
Listening
to Tommy Flannigan play “Verdandi” from Sea
Changes (ECD22191) as I have thousands of
times, I was set into a full body mojo as the
Flannigan Trio was seriously on the same
musical page. In particular, George Maraz’s
frenzied bass runs were nicely resolved, with
one note seamlessly connected to the other
while preserving each notes fingering and
transient.
If
that didn’t convince me, Extreme playing “War
Heads” from III
Sides to Every Story (A&M31454), left
absolutely no doubt. This track has a
ferocious kick drum driven pace that when
properly reproduced, can lay waste to an
unsuspecting driver. The DA-218 did a very
good job at allowing the power and control of
the drum while preserving whatever natural
timber of the bass drum that one may find on a
rock recording of the early nineties.
Hungering for more, in went Stevie Ray
Vaughn’s Soul to Soul, which despite
it’s many sonic failings, The DA-218 dug out
the swagger of Stevie Ray which had to that
point, been MIA .The music on this disc. On
track three “Look at little sister” the DA-218
manages to turn hamburger back into a cow (or
digits back into an analog waveform if you
will) allowing not only the lower registers to
sync up, but keeping all the transients of
the, drums, guitar and cymbals superbly clean
leaving a “happening in real time” feel
in it’s wake. It should be said that with the
CD12 as a transport, the bass of the DA-218 is
rounder and warmer, while the inclusion of the
Gryphon Mikado gave the bass a tighter and
faster presentation.
Now Mr. Dodson was adamant that the DA-218
captures the analog experience in a way no
other digital processor can. Discounting for
manufacturers hype, I was expecting at least a
good measure of this quality considering the
very dear $7,995 price tag. While I cannot
ultimately testify that the DA-218 bests all
processors in the quest for the “tastes like
analog” crown, I can safely say the DA-218 has
a way with dimension, timbre and color, high
frequency sweetness without the loss of detail
and space which are all hallmarks of great
analogue. Recording after recording reveals a
wealth of space and air that one hardly
associates with even the better digital
available.
Listening
to the Cowboy Junkies’ Margo Timmons sing
“Something More” from Lay it down
(GEFD24953) I was struck by how open airy and
down right ethereal her voice was. The same
holds true when reproducing the trumpet.
Getting the horn right is one of the hardest
things a system can attempt, especially if you
are expecting realistic dynamics without the
penalty of compression, flattening of image
dimension and hardening of timbre. With the
DA-218 in the chain, Roy Hargrove’s trumpet on
“Laura” from the Roy Hargrove/Christian
McBride/Steven Scott Trio CD (Verve 314
527 907-2) entitled Parker’s Mood is kissed
with a sweetness and seamless dynamic scale. T he
mechanical nature of the system sounds less
hard and the illusion of a real trumpet
remains complete and intact. This, in turn,
kept my attention and involvement in the music
intact.
The main complaint with digital is that its
distortions being of a non-harmonic nature,
yank the listener by the scruff of the neck
right out of the musical flow. As a result,
listener fatigue sets in quickly sending them
scurrying back to the turntable. The DA-218
goes a long way toward curing those ills. On a
recent visit, Mike Farnsworth of Talon Audio
commented that the system “sounded like analog
and nothing like digital.” Those were his
unprompted words. Soon after our beloved
publisher Clement Perry made his bi-monthly
visit with a few new music samplers in hand.
After several tracks, Clement was rather
stunned as to the analog-like ease and
naturalness of the system. Yes, the deck was
stacked in favor of the DA-218 as all the
components I have allow for a fairly good
measure of transparency and neutrality without
the sacrifice of musicality. Some would argue
that transparency inherently defines
musicality, and in theory I would agree, in
practice however, most systems that are
claimed to be transparent first and foremost
usually don’t sound much like music to these
ears. That said, the DA-218 does allow for
both great overall transparency and seamless
tonal neutrality, which in conjunction with my
system, produces greater musicality and yes, a
far more analog than digital experience.
A comparison to the Linn CD12 powered by its
own internal DAC is well worth a go. On its
own merits, the CD12 is unparalleled for its
treble smoothness, truth of timbre and
resolving power without the penalty of
forwardness or brightness. It also images in a
totally natural way, avoiding any flattening
or etch. The knock on it would be that it can
be a tad dynamically polite and laid back,
though no one who has heard it in the last
five years has really complained. However, by
adding the DA-218 to the signal via the
Virtual Dynamics balanced digital interconnect
and partnering Master series power chord, the
sound became more incisive and “visible”.
Instrumental color improved, but it was the
sound stage that really shocked me. Images
seemed to burst forth, creating an almost
“exploded” view into the stage. As a result, I
was compelled to spread the Talon Firebirds
apart an extra foot or two in order to
accommodate the robust soundstaging. Another
quality truly unique to the CD12 is its
ability to “see through” instrumental
textures. Here the DA-218 proved the CD12 to
be rather ghostlike or vague compared to the
densely colored images presented by the
DA-218.
Late in the game, as mentioned earlier, I
received the new Gryphon Mikado CD player,
what a beauty. Used as a transport the combo
yielded spectacular results. The shocking
level of realism and flat out musical magic
has elevated the performance of the system to
a level I never thought possible. I will get
into the specific traits the Mikado brings to
the table in a follow-up to Clement’s review.
Also shortly afterward, Silversmith’s
Palladium digital cable showed up at my door.
What an embarrassment of riches!. My positive
reactions to the Palladium line stayed true
with the digital link. Capturing an uncanny
level of information while revealing such
natural texture and color moved the
performance of the Dodson/Mikado combination
in the direction of the organic, if a tad less
incisive.
As I was wrapping up the review, several sets
of Final Labs Durama-II isolation devices
arrived. I realized the DA-218 enjoys being
isolated from bad vibes pretty early on in the
review (I guess I should have mentioned that).
These little brass jewels use a ball bearing
sandwiched between two puck shaped “cups.”
When placed under the DA-218, the sound gained
focus and opened up, yielding a smoother
treble and greater overall ease. At $99 for a
set of four, these are a no brainier.
The DA-218 has another trick up its sleeve:
the ability to process DVD audio.
Now I have not been a huge proponent of
the new medium, as I have not heard a product
with the pedigree of the DA-218. With the help
of the much-heralded Linn Unidisk 1.1,
I
would get a full measure of the DA-218.
Popping in Red Rodney 1957
(DAD1003) I was immediately struck with the
level of palpability and color rendered.
Compared to the red book standard, the DVD
Audio was clearly superior. All the traits of
the DA-218 held true, there was just more of a
good thing, and in this case more was better.
Next came Deep Purple’s Machine Head
(R97664). I have been listening to this disc
since I was 12 years old (Oh my God, that’s
thirty years!). The red book version is
excellent, great impact, swing to spare, and a
grain and glare free high end. Through the
DA-218, it was like being there in concert. My
personal anthem “Lazy” was just a hoot.
“Highway Star” brought me back to my bass
playing days in high school and college. Who
ever thought Deep Purple could be so
sentimental. The direct connection to the
music was stunning. This is high-rez done
right, finally! I look forward to sampling
many more DVD audio discs in the very near
future.
DaDaDaDa DAC’s All
Folks!
Yes, I love the Linn CD12. We have had a great
relationship over the years and may well stay
together for some time to come. But I have to
admit, it was great fun working the Dodson
Audio Model 218 into the mix. Call it the
three-way I will (probably) never have in real
life.
As for its application, I can’t imagine a
front-end short of the highest of high-end
esoterica that the Model 218 couldn’t improve
upon, and possibly by a large measure. Even
top of the heap rigs may well find the DA-218
an unexpected step up. As I sit here listening
to Tommy Flannigan, this time on Live at the
Village Vanguard, it dawns on me yet again, I
could sit here and listen to music all day and
well into the night. Analogue? Digital? With
the DA-218, those questions evaporate into the
ether replaced by what to listen to next? What
music to explore next? If you are a
well-healed analog devotee who has adopted
digital more as matter of convenience than
ultimate musical enjoyment, or a digiphile
looking to make the leap from the ordinary to
the extraordinary, you may find a one-two
punch for both red book CD and DVD audio in
the Dodson Audio DA-218, I sure did.
