Agear: His stands are made with a 1/4" of proprietary material sandwiched between two 1/2" sheets of acrylic. There is a wire to be plugged into the system powerstrip, but it only actively connects to ground so no electricity is drawn from the wall. Posted the following reaction on his FB wall (business). At this point Alan had already stated that a component on his stand was allowed to operate entirely above its own internal noisefloor:
"Something else I discovered that I didn't expect. Using a modified DEQ2496 as a DAC. Stock or modified, there was always a slight dynamic penalty imposed when using the digital parametric EQ. Choosing a frequency and slope (or q) is no problem - until you go to move the level away from 0 db, either up or down. At the minimum step of .5 db there is always a noticeable reduction in dynamics that extends the width of the slope you've selected, but, oddly, no more than that. For example, if you choose a q of 3 octaves you'll hear that reduction in dynamics within that 3 octave band, but not beyond. Once you go beyond the first .5 db there is no additional reduction in dynamics no matter what level you choose, but there is always that initial penalty imposed as soon as you move away from 0 db. Normally this is a minor annoyance by itself, but if you select nearby center frequencies that have overlapping slopes, then you take multiple hits in that one general area and that's when it all begins to be a real limitation on the sound. As a matter of practice, I've learned to use the EQ for as broad and as gentle a curve as possible with the fewest number of overlapping center frequencies as possible to minimize all this (not really a bad rule of thumb with analog EQ for that matter anyway). But, a few hours after placing the DAC on the Q-stand, I noticed I could no longer hear this effect. If it is there at all, it is no longer audible. Then I remembered what you said Alan, that Q-stand allows the component to operate, in effect, free and clear of it's own internal noise floor (or words to that effect). Huh...no more problem."
This was Alan's reply:
"John - In effect what you are experiencing with the Behringer is its version of digital circuit clipping most people confuse clipping with db output but clipping also applies to all internal circuitry amplitudes .so increasing/decreasing causes ringing artifacts to be super imposed on the signal but using the qCell or Tri-Cell platform under the component eliminates the ringing artifact at the source which quickly becomes apparent via playback just imagine the potential for project quality when this technology is applied from studio capture to playback".
Afterward, I then realized that the slightly increased tolerance of the main digital input meters on the DEQ (which hadn't been touched) was not my imagination playing tricks on me after all. This is also about the best way I'm aware of to take a direct shot at reducing digital "self noise" inside a component.
But, it was the overall change in sound quality that did it for me...far better vocal and instrumental hues and textures and ALL that good stuff!
