From China With
Love … and Lower Prices!
During the course of your life you’ve probably dated
somebody who at first glance seemed like a rather
simple and mild-mannered person who would be nice to
hang-out with but was probably not going to set your
world on fire. The next thing you know, that person’s
got you on chapter 13 of The Karma Sutra and you’re
twisting your body into positions that would make a
yoga instructor feel squeamish. That sort of describes
my first experience with the Chinese-built, Xindak
Audio XA3200S vacuum tube preamp … Okay, so maybe it
wasn’t quite that wild, but keep reading anyway.
Xindak is one of a number of Chinese high-end audio
manufacturers that has been making a splash in the
U.S. audio market as of late. As you may have read in
my Usher Audio AC-10 loudspeaker review, famed
loudspeaker designer Dr. Joseph D’Appolito was quoted
as saying: “Eastern manufacturing costs are much,
much lower,” and “ … eastern manufacturing technology
has caught up with the West while
most of their plants are much newer and more
efficient. This is something the rest of the high-end
audio manufacturing world will have to deal with.”
Jay Bertrand, Xindak’s U.S. distributor agrees. “It’s
a joke when you look at the prices of some things
being made here versus what is being produced in
China,” said Bertrand. “They’re producing
equipment there that would easily cost two to three
times the money if it were made here.” Besides
Usher and Xindak, other companies such as Ming-Da,
Shanling, Sheng Ya (a.k.a. Vincent Audio), and even
the much ballyhooed Antique Sound Labs, are gaining a
lot of notice in the audiophile press worldwide and
amongst U.S. audiophiles. Products like the Xindak
XA3200S are a big reason why. Its elegant styling and
agreeable price belie its wonderful sonics.
Humble Looking Beginnings
The XA3200S is a model of deceptive simplicity. On the
left side of it’s ¼” thick brushed silver aluminum
faceplate are a soft-touch power button and an IR
remote sensor. In the center are four small line
source selection buttons with tiny LEDs above them
labeled “S-1” thru “S-4”. On the right is a large
volume control knob. The back of the unit is just as
understated with four sets of gold-plated RCA inputs,
two sets of outputs and a power cord receptacle.
That’s it! No digital volume and source selection
display. No artistic sculpting or engraving. No high
gloss finish or gold-plated accents, just a plain old
preamp. There in lies its deception. This is not a
plain preamp.
The first thing you notice is this piece’s quality of
construction and heft when you pick it up. You
wouldn't think for this price that you’d get something
this well made and, in a minimalist sort of way, nice
looking. You definitely get more than your money’s
worth with this piece of gear. It's solid, well-built,
no loose connectors or switches to worry about.
Everything was easy to read on the preamp and setting
it up is fairly straightforward.
Under The Hood
According to the manufacturer, the XA3200S uses two
5670 or 6N3 electron tubes connected in-parallel into
a Shunt-Regulated Push-Pull (SRPP) path to amplify, at
the same time it uses one SRPP constituted by a 12AU7
tube for output. Also, it adopts the direct-coupled
inter-valve, which gives relatively wide frequency
response (10Hz-100kHz, @1dB)
and good dynamic and low-frequency control abilities.
In addition, the power supply of this unit takes the
characteristics of earlier XA3200 designs, adopting VT
commutation and voltage-stabilizing, which makes
better matching between the inherent resistance,
performance and amplifying circuit. The control
section uses a single-chip microcomputer. Volume
control is accomplished via an imported ALPS motor
potentiometer. The sound source selectively adopts
relay to realize the soft-touch switchover. All of
these functions can also be used via a remote control
made from a wire-drawing die of aluminum alloy. The
operations are convenient, the reliability and
fidelity are better, and handling is easier.
Also, the materials used in the XA3200S are of the
finest quality. DALE resistors, WIMA, RIFA, and
special Xindak MKP capacitors, premium gold and silver
plated signal wires. On the interior, zinc-coated
plates are used to separate the power supply and
amplifying circuit. This means the mechanical strength
and electromagnetic interference resistance capability
of the unit is outstanding. The only things that this
unit is lacking are balanced (XLR) input and output
capability. Then again, if you haven’t bought into the
hype around balanced designs you won’t miss it here
and will appreciate Xindak’s willingness to ignore it
and keep the costs of this unit down.
Let’s Play Some Tunes!
Call it luck, call it serendipity, but I had just
returned from my monthly spending spree at Tower
Records when the delivery truck rolled up and dropped
off the package containing the Xindak preamp. I had
just bought a couple of discs off the recommendation
of some of my Stereo Times brethren. After I got the
unit unpacked, I installed it into a system comprised
of the Electrocompaniet EMC-1 CD player, a pair of EC
AW220 mono amps, and the Dynaudio Contour S5.4
loudspeakers. The system was wired with Virtual
Dynamics’ “Nite” series speaker cables, interconnects,
and power cords.
Jay Bertrand of Bertrand Audio Imports, the U.S.
distributor for Xindak, was kind enough to send me a
unit that was already broken in, so after few hours of
warm up, I was able to get right into listening to
this unit. One of the discs I bought was Rosario
Giuliani’s “Mr. Dodo” [FDM 36636-2]. After I
got done snickering at the title of this disc I found
myself subconsciously tapping my toes and bobbing my
head to the opening track for which this disc is
named. It’s a dynamic and layered recording that
features Giuliani’s splendid yet hard driving
saxaphone. But what really grabbed me was the ice-cold
piano work of Pietro Lusso. It was obviously free
formed but it was also very lucid and was the perfect
complement to Giuliani’s performance. It takes a
talented preamp to decipher those two different types
of sounds within the same recording and the Xindak did
it extremely well.
I have long been a believer that nothing reproduces
the delicacy and air of the piano the way that tubes
do. One of my favorite discs for listening to the
sheer beauty of the piano is Patrick Noland’s “Gathering
Light” [naimcd 011]. Ken Christianson, who to my
ears captures all of the pristine sweetness of live,
un-amplified music as well as any engineer around,
engineered this recording for the Naim Label. If you
love piano music, un-accompanied piano music, this
recording would be well worth seeking out. But you
probably won’t find it available at your local music
store so I’d suggest visiting Naim Audio’s website or
just call Ken himself at his audiophile hangout, Pro
Musica in Chicago. Track 3 from Gathering Light is
called Entranced Within Us. It is one of those
performances that seems to transport you. The XA3200S
fleshes out that wondrous quality from the first note.
In the dead-silence of my listening room I could hear
Noland’s foot tapping the pedals of his nine foot
Steinway. The decay of the notes from felt-covered
hammers hitting strings was captured to near
perfection (This is still a digital recording. Lucky
me, I got to hear it on Ken’s Nagra 4S tape recorder.
Big difference.).
A Quick Comparison
I compared the Xindak to my Talon Audio-modified
Electrocompaniet EC4.7 solid-state preamp which is
also in the $1,500 to $2,000 price range. The
differences were not at all unexpected. The Xindak’s
tube qualities were immediately apparent in the
midrange and treble performance. The sense of air and
warmth was somewhat more palatable through the Xindak
than through the EC, particularly on voices and some
intimate jazz recordings. But when the going got rough
– as in when I put on George Clinton & The P-Funk All
Stars’ “Dope Dogs” [Dogone Records DOG9816] –
the EC kept it’s composure at the higher,
brain-bending volume levels that this
funk/metal/hip-hop disc thrives on. Especially the
opening track, Dog Star which features the driving
guitar work of the legendary Eddie “Maggot Brain”
Hazel. But when the music and volume level came back
down to Earth, so did the Xindak’s mastery of the
delicacies of live music.
The bass was not the tightest I’ve heard, especially
when pushed to louder than normal levels. But the high
frequencies are extended and you never get that
feeling of mid-bass over-emphasis that you can get
with some less expensive designs (and some much more
expensive designs for that matter). The stage was very
wide and surprisingly deep. Spatial clues were clearly
evident around the performers and the instruments. It
renders a lot of detail but was neither etched nor
fatiguing. I felt it played jazz and classical music
equally well and found it hard to seriously criticize
on any count.
Conclusion
I could easily live with this preamp as my reference,
which shows just how much I enjoyed it. The bottom
line is that if you’re just starting to put together a
system, and want an excellent control unit that will
allow you to put more money into other parts of your
system, the Xindak XA3200S should go on the top of
your short list of things to do. But be sure to do so
before meeting someone who will have you do chapter 13
of the Karma Sutra or you may not have much time to
enjoy it. In terms of cost, features and performance,
I think it's the best preamp you can buy for under
$2,000.
