Since DaviSound has always accentuated a design philosophy of
extracting and applying only the best, most logical, methods and principles
from both the "subjective" and the "objective" audio schools of
thought, it should come as no surprise that DaviSound is announcing a new
"line" of audio components for "high end" audiophile enthusiasts.
Now this so-called "line" will be very short indeed since we will
likely only offer one to three of these prefabricated, hand-crafted audio masterpieces per year,
each representing numerous hours of meticulous effort, spread over
several months, until we are satisfied that the result is a piece that we are
ready to launch into posterity.
This will, likely, be all the prefabrications that we will have time for in addition to the custom DaviSheen commissions that come alongside our constantly on-going, made-to-order pro audio Tool Box creations.
While DaviSound, an original audio electronics "objectivist", is always
at the forefront of disclaiming and exposing "unsound" (pun optional!)
myths and fads, as well as downright frauds, offered at the gullible in
today's audio marketplace; we, on the other hand, also emphasize, and
document on our web pages, that we do many very REAL, esoteric,
therefore "subjective", things in our own fabrication methods which we know DO
make a difference in both the audio quality and the longevity of our
hand-made audio components.
Now PLEASE do NOT misconstrue our statements here as the kind of empty "hype"
seen on many audiophile (audiophool?) marketing sites! Our
highly unique methods of building audio components, most definitely, DO set
DaviSound apart from ANY other manufacturer in today's marketplace!
These distinctions will be readily recognized if you study our website and, especially ...
when you own our products!
read about all of them, here on this website. In addition to this area ...
See ... Design Philosopy ...
DaviStatements ... DaviStories ... and FAQs ...
as well as the general descriptions of all our
pro audio Tool Boxes and the special techniques
behind every one of them.
We also now have a dedicated technical page, linked from this "DaviSheen" page, whereby we will talk openly, and at length, about some of the specific circuit topologies and design techniques that we will be utilizing in our more "revolutionary", commercial vacuum tube offerings!
This new Technical discussion page is now being developed on a continuing basis.

"Audiophiles" or "Audiophools"?
As an example of our "draw the line" approach to audiophile high-end
audio, while we do not feel it necessary to advocate certain faddish,
brand-name (always the most costly, of course) resistors and capacitors,
or hookup WIRE (audio guru heaven forbid), we do, at the same time,
acknowledge that designers should ALWAYS employ the truly best
available, high quality components such as low noise, low tolerance resistors
and film capacitors, and proven, hand-soldered circuit laying
There is NO valid reason, no SOUND (that pun again) reason, to
advocate less than the best generically available componentry in the
fabrication of audio electronics circuitry. And, yes, at DaviSound we do
utilize SILVER solder ... silver being the most electrically conductive and
corosion resistant, practical alloy ... it is simply the logically
better choice in solder for audio electronics ... period. We use it for
that reason and not so that we might claim it as one more "salespitch"
in the direction of trendy "audiophools"!
Obviously, the acronym "DaviSheen" implies vacuum tube technology.
Why would DaviSound, now a globally recognized innovator in true precision,
TRANSPARENT, solid-state, pro audio circuit technique, digress to tube
circuit design just to accomodate a niche audiophile demand?
Well, let's just say we believe, for several reasons, that tube audio still has its place!
Now, by way of extensive elaboration on that, let me start by clarifying
that I have heard, and in many cases tested, most all typical tube technology
and topologies past and present. Having done so, and having lived with
our super clean, accurate solid state designs, there is simply NO ONE-
NO WAY who can make a valid claim to me that most traditional (emphasis on "most traditional"!) tube-based circuitry can
be made, under ANY circumstances or conditions, to sound quite as "clean
and accurate" as our DaviSound solid-state MasterPiece modules! A few
of these traditional tube topologies, with select tubes and quite a cumbersome power supply
support effort, can come very CLOSE in some cases. But even in the best of
them, most designers and users, traditionally, prefer to allow that subtle "harmonic additive", to be detectable, at
least to some extent, or to greater extent, as the case may be.
I can listen to a known, accurate signal source amplified through our
TB-8 lab reference amplifiers and get a very "pristine", highly accurate
replica of that source. If I then run the same signal through most ANY of the many available, manufactured tube
preamps, or line level amps, ahead of the TB-8, there is a coloration that is ALWAYS double-blind A/B detectable to me. I
pretty well bat a thousand on it! You'll just have to trust me on this
claim, of course, but the important thing is, I myself, know it to be
true so I cannot kid myself that these outside tube designs "sound as accurate" as the TB-8 alone amplifying a source without the other gear in the
chain! Of course, the same can be said for many of the "outside" solid state offerings in the marketplace also.
So, once again, how does this designer justify the time and expense of
building and presenting select tube audio preamplifiers and processors
alongside his true state-of-the-art solid state designs?
Keep in mind
this is the same designer who lives by the philosophy in pro audio gear
design that audio equipment should NOT HAVE A "SOUND" unto itself but
only faithfully pass, reproduce or amplify the signal source presented
Well, first of all ...
We justify it because we know it is not the tubes themselves that cause these audible artifacts but, rather the designs using them, as will be elaborated further below.
However, we can also justify some of the more traditional applications to some degree because there are simply so many people who happen to
ENJOY, and desire, listening to and using a well designed
vacuum tube audio amplifier that retains at least some, subtle, traditional 2nd harmonic content!
As long as we emphasize the disclaimer to our readers that tube circuitry is NOT some kind of panacea unto itself ...
and as long as we widely separate and
disassociate ourselves from such high-end "experts" as the one who comments on
his website that "high end audiophiles", by definition, adhere to the
belief that audio can only be faithfully reproduced elctronically inside a
once those important distinctions are well established ...
then, and only then, is it valid to offer a tube design for
the serious consideration
of the serious audio world.
Actually, perhaps the simplest way to explain it is to say ...
we do it
for the fun of it ...
for the simple enjoyment and satisfaction of seeing a piece employing "class glass" come to fruition!
I, too, enjoy the "light therapy" offered by the glow of the tubes while they work!
There are those who cherish the "sound" of a simple tube circuit, which employs no corrective negative feedback, for the very
subtleties we just described and they need make no apology for that!
In fact, so long as the admit that they KNOW that tube topologies,
especially those operating without negative feedback, WILL, invariably, have
a harmonic related "sound", albeit extremely subtle in some cases, then
they even have the right to try and "sell" the rest of us on the idea
of trying such traditional tube based processors, amplifiers and control centers for
ourselves. But, they must always keep in mind that they do NOT have the
right to make unsubstantiated claims that this "sound" they distinguish,
and find so preferable, is actually some superior fidelity
characteristic inherent to tube amplification when, in fact, it is just the
Then, for those of us "tube lovers" who prefer to apply modern circuit design knowledge by simply using tubes in our circuits on occasion, instead of transistors or op-amps, then we, too, certainly need make no apology for that. In fact, it is logical to insist that that we may even have the best argument for swaying the "old conservatives" to give our methods a listen rather than the other way around!
This is because the very same, wonderful linear attributes that make tubes so attractive
in simple circuits make them even MORE superb when incorporated into modern circuit
design and application!
With "DaviSheen" designs ...
we plan to offer fabrications for both schools of thought!
Now, with all of that documented and, hopefully, well understood,
DaviSound is pleased to offer ...
for those who would enjoy it and appreciate all the effort
behind it ...
our "DaviSheen" concept in preamps and audio control centers!
In the months to follow this January, 2005 writing, DaviSound will
offer select pieces in the "DaviSheen" format. These will always be
individually described and, most likely, introduced on our News Updates page,
or somewhere on our website, weeks prior to being auctioned to the
highest bidder on eBay.
Typically they will be "theme" pieces of handmade functional art and
certainly, by nature of their rarity, collectible items as well.
Let me also point out here that it is NOT necessary to wait for the
next, finished piece to be put up for auction in order to own one. These
items can also be commissioned on a custom, priority basis for the
discriminating, elitist, at any time. We will gladly supply custom quotes
on an individual basis, entertaining extensive, detailed mutual email
correspondence documenting such a project, for any serious, qualified
Vacuum tube audio lovers each has his/her own "addiction" or "hook".
Besides the "sound distinctions" already belabored herein, often it is the satisfaction of the simplicity of a single ended, Class A , Triode audio stage. Sometimes it is the "warm glow" of the filaments or even the smell from the heaters and the warm phenolics! Maybe it is just the remembrance of a bygone era or, more likely ...
a combination of all the above.
But ... whatever YOUR particular fascination for "bottled audio", we urge you to take a close look, and listen, for yourself at the warm glow of "DaviSheen Bottled Beauty".
