Power Cord Revelation

With my Pass Lans x350.5 I have a Virtual Dynamics Rev2 power cord on it and it is a big improvement over a standard cord. The improvement is in dynamics and bass texture.
I also have My Amp plugged into a dedicated 30A circuit.

I have several Audiophiles using DCCA pc's on their Pass amplifiers and very satisfied with the sonic results. Really comes down to what you want to hear. Don DCCA

I think that there are reasonable explanations for how custom power cords can positively impact the performance of even (or especially) high performance audio equipment. They have mostly to do with the electrical environment OUTSIDE the components in your system. This topic has received much attention on Audiogon and elsewhere (see this recent thread for example http://forum.audiogon.com/cgi-bin/fr.pl?fcabl&1190049515&openusid&zzKnownothing&4&&).

Also see the Guerrilla Audio site for the most logical description I have seen from any vender as to how well designed PCs work to improve performance

Good luck.

Right now,even switching to tubes,I used the DCCA cables
they are that good, they flesh out every music in my
system...without brightness at all.Thats what I like from
this power cords.

Perhaps, in addition to transmitting the power better, they also serve as a filter and compensate for and clean up the grunge of miles of cable that end up at the wall and keep it clean from conditioner to component. After all is said and done, audio is transforming electricity (energy) to mecanical energy (speakers ad sound). Garbage in - garbage out. Bottom line, I believe; and the acid test, my wife can tell when I put in new PC.
