Since I started this thread I probably should close it out. Bottom line is these Lessloss power cords do seem to make a positive difference when used to power the front end of a system. I didn't try it on my TT as that seemed almost silly (what's it gonna do, make the platter motor sound better?

) but on my sacd/cd player it did give vocals more weight and depth, taking off any slight edges that may have been there. During the A/B process I tried to listen to specific high or low frequency parts of the recording but since our sonic memories tend to be woefully short, that effort was in vain. So my comments regarding vocals were the only way I can describe what essentially is the indescribable, although that never seems to dissuade many of our esteemed audio "reviewers" from resorting the sonic-speak rhetoric: bloom, air, liquidity...ad nauseum. I swore not to go there so hopefully my use of
weight and
depth didn't borrow from the over-used rhetoric. I compared the Lessloss to the Shunyata Pythons and thought the results were virtually identical so I'd have to say that if one is considering either, the fact that the Lessloss is half the price of the Shunyata may have to enter into the purchase decision. One other tidbit of info is that you seldom see a Lessloss PC in the Audiogon classifieds and I would have to assume that there a lots of their cables out there because they do advertise rather heavily.
One other point that could have influenced what I heard was the fact that my VR5 Anniversary speakers continue to break in and just recently they seem to have reached a sort of break in milestone with the soundstage expanding significantly. The low end is more more pronounced now and it isn't my imagination, trust me. But that aside, when I switched between my DIY power cords and the Lessloss and Shunyata there was a sonic difference however subtle.
If you are a skeptic about all this I can certainly understand as I have been one all along myself. I am not trying to convert believers here, merely offering what I have experienced. PC substitution should be considered one of the last tweaks in a system and probably only in systems capable of a high degree of resolution. Most may find it subtle at best.
