Just wanted to pitch in with my results on the V.D. cords.
I recently replaced my Custom Power Model 11 with the V.D. "Audition" on my amp. After thorough break in, a DEFINATE improvement, in all areas. Especially notice a more "relaxed", and fluid presentation, with a much better defined (& w-i-d-e-r) soundstage.
Next, just for "grins", I replaced my Silver Audio Power Burst with the V.D. "Power 3" cord, on my PS P300. Didn't really expect much here, but again, same type of improvements -- blacker background, even further reducing the "strain" and glare, leaving a more relaxed, easier to listen to presenation. All with NO loss of detail or "rounding off" of the highs. All from a $50.oo cable!!
This guy Rick must be doing something right, and at his "promotional" prices he's got going right now, I would urge anyone & evryone to give 'em a try, before these cables inevitably "catch on", and he wisely raises his prices.
I guess as mentioned abaove, system synergy has a lot to due with it. I know I'M completely sold.
