DaviSound ... Unique by Design

A little "DaviSimple 'Philosophication' " ...

We were audio "purists" from the beginning. Our original goal was, in the mid seventies, to build equipment for use in our own studios which would be as TRANSPARENT and as "COLORLESS" as possible.

You've heard the phrase, "straight wire with gain" many times (of course, some of us now know that even a simple "straight wire" can "color" the audio under certain conditions!). We were among the first to aspire to this design ideal.
And, in principle ...
truly transparent audio chains are still the foundation
of our primary audio equipment.

As you read further, you will discover that we do many unique things in our circuit design and fabrication techniques which result in audio equipment that is UNIQUELY SUPERIOR in many ways!

"LOW END" or "HIGH END" ? As the wise old sage replied when asked a meditative question ... "It all depends" ... In other words ...we are SUBJECTIVELY OBJECTIVE in our approach!

We certainly do not believe in "mystical" properties at work in audio electronics but we DO know that some simple, albeit UNUSUAL, methods can make a difference in both AUDIO QUALITY and resulting circuitry which will last almost indefinitely! After all, it is these very UNIQUE methods that give us our own niche and cause the truly knowledgable to seek us out for our
hand-laid circuitry and fabrication methods!

"STAR" WARS? - This "war" between audio subjectivists and objectivists has been going on almost since the beginning of audio and, likely, will continue to do so. We prefer to recognize a "Grey Area". A very real example of what we mean:

We KNOW for a fact that placing a brick beside (or on top of) your audio amp will NOT make a difference in the "sound" of the amp (an actual claim by one subjective extremist in a publication!)- unless, of course, it happens to dampen an acoustical/mechanical cabinet rattle!

On the other hand, we also know that there are very sound, common sense reasons why our circuit fabrication methods, which use direct, point-to-point wiring technique, with components mechanically connected as well as soldered, are far superior to the industry "standard" method whereby components are
flow-soldered to PCB traces!

This is so, if for no other reason (and there ARE other reasons!) than the fact that one solder joint is better than two and a direct connection is ALWAYS better than an indirect one - ( lead to lead ... as opposed to lead to trace, then trace to lead).

In the early days, we pioneered our own version of "surface mount technology". We used normal sized components soldered to traces and pads which were located on TOP of the PCB, usually on double sided circuit boards
with the underside used as a shielding ground plane.

Nowadays, for a variety of reasons, including the logical advantage of direct, point to point wiring mentioned above, we build many of our circuits utilizing what we call "air suspension" ("AIR BORN"!) technique. This entails direct soldering component leads to each other after having first formed a sound, mechanical connection, and encasing the whole circuit block within a plastic case.

This method was born out of a personal distaste for the wasteful, subtractive process of circuit board etching whereby harsh chemicals are utilized to wash away the copper you don't want (which is most of the copper on a clad board) leaving a small amount for the PCB traces and pads.
Our new method also solved a second problem for us as well.


We finally realized that many of our original audio circuits, now perfected after many years of evolved research and fine tuning, would need to be "potted" (embedded in silicon) for proprietary purposes. This was because, in at least one verifiable instance, a major manufacturer had "borrowed" one of our original treasures and was attempting to manufacture it almost component for component! For many reasons in the real world of competitive circuit design, patents simply do not work well in these areas nowadays. Therefore, we now "pot" many of our most exclusive, hand-laid circuits into building-block modules with the contents secure and protected, in more ways than one!


When sub modules are interconnected within a unit, we do NOT use plug-in connectors! Plug-in connectors, subject to oxidation, corrosion, warpage and jitter, are among the main causes of problems in most manufactured products over time!

Most forthright mass production manufacturers will admit that their laboratory test-bench prototypes ALWAYS out perform to some degree, and outlast to a large degree, the subsequent production-run models inspired by these prototypes!

This is largely because most mass produced products are designed with two basic main priorities foremost in mind. These priorities for the manufacturer are "ease of assembly" on a production line and "ease of servicing" when the product comes back to the factory service department due to failure.

Ironically, it is most often these very things utilized for "ease of servicing" which caused the product to wind up needing the service (things like PCB plug/socket contacts and modular plug-in connectors for example)!

Nowadays, as consumers have become increasingly aware of some of the pitfalls of modular manufacturing methods, we hear a lot of "propaganda"
about the benefits of "GOLD PLATED" connectors.

Large mass producers HAVE to rely on some form of modular plug-in system since they always use the assembly line method in some variation.
Furthermore, if a circuit board fails, it has to be designed for "unplug and replace"
since that is all their technicians are trained to do!


So, WHAT is better than a GOLD plug-in connector?
plug-in connector, that's what!

Our circuit boards and sub modules are HARDWIRED to each other and to their various control assemblies. This requires KNOWLEDGABLE assembly persons taking tedious hours to put a piece together.
But, the end result is well worth the time investment!


The result is circuitry that will last a lifetime (or MANY lifetimes)
without failure or service!

Certainly we use strict patterns, and proven procedures but every piece of our equipment, and its circuitry, is individually hard-wired and hand soldered!

Over the years, the specifications for various products, quoted by various manufacturers, have become nearly meaningless. In earlier times this was largely because of something now known as "specsmanship". That refers to the dubious "art" of manipulating specification descriptions to suit one's own purpose in making one's own product look superior on paper.

Fortunately, nowadays, MOST professional products all have very similar, respectable electrical specifications when measured by traditional standards. What, then, separates the "sonics" of one product from the "sonics" of another? We like to think that, in our case, the highly defined audio that "jumps out at you" (as one satisfied user once told us) is due in part to some of the very techniques we're bringing to your attention on this page!

Unless otherwise stated for a particular device, ALL of our units (Tool Boxes and custom built units) feature COMBINED noise and distortion products that fall into the residuals of today's best test equipment (typically .001% or better!)!
This means performance approaching the theoretical ideal and
certainly near the limits of today's technology .

Typical maximum signal levels are now right at 32dBu due to our new circuitry which allows much higher power supply voltages! Full power bandwidth of these circuits measures ruler flat from 1.6HZ to beyond 30KHZ with intentional, gentle roll-off thereafter to minimize supersonic and RF distortions which could, otherwise, interfere and interact with signals within the audio range
(-6dB at 120khz and 6 dB down per octave thereafter).


Normal input impedances are 50Kohms, or greater, for non-loading, bridging capability (line level equipment) and output impedances are low at
100 ohms, or less, for maximum drive capability.

All signal shaping capacitors are high quality, test selected, film types with any minimal required electrolytics being recent issue, high-tech, discreetly formed bi-polar configurations with proper DC bias employed. Resistors are matched, low noise, metal film types in all critical signal areas.

DaviSound circuit assembly techniques, like our enclosures and control panels, are truly UNIQUE BY DESIGN and quite unlike what is accepted as standard in the electronics industry of today. Our small staff of craftpersons routinely construct some of the most dependable ...
consistently performing audio/video circuitry available anywhere today!

So, if you ever have occasion to look inside one of our "TOOL BOXES", or other gear, and you notice tightly twisted pairs of heavy gauge wire directly interconnecting modules, boards and controls as opposed to thin PCB traces, you will know that it's because there are very good, very real reasons ...
very SOUND reasons ... why our way is better.
And they are based on good common sense ... not mystical, guru magic!
