I was very skeptical about power cables and the differences they supposedly made in audio applications. I've owned a first generation Shunyata Venom cord for a few years and was never really able to tell the difference between it and a variety of other cords including the ubiquitous Volex and a few other nondescript ones I had lying around. I basically kept it mostly for its look and figured it couldn't be any worse than a $15 Volex.
Last weekend I was at an audio dealer and inquired, mostly out of curiosity, about the Venom 3. The sales guy seemed indifferent to it but suggested that I take home a $600 Siltech SPX-20 demo cable "just to try it out"
I told him I was very skeptical and in any case there was no way that I would even consider forking over 600 bucks for a piece of wire. Well it turns out that the SPX-20 made a huge difference in the sound of my EE DAC - way more than any tube rolling could. Sound stage, noise floor, separation and detail were all improved. This dispels any doubts I had about power cables making a difference. They do!
Unfortunately in this case while the SPX-20 made everything wide open and crystal clear it also reduced the bass considerably and make my system sound very thin - no doubt about it.
So at least in my system, regardless of price, the $100 Venom and the $15 Volex win hands down.
Now that I'm convinced power cables DO make a difference all I need to do is to find one that will make things sound better - hopefully it won't cost $600 either.
