Wow. Just......wow.\n\nPower cables I could see actually improving the clarity of the signal. Rocks? What the.........?\n\n\nHow do you "see" power cables improving the signal? All it does is carry electricity to your audio device....the audio device should be designed so as to use that electricity without issue. OTOH that's what makes cable audiophoolery sell well.....it's somewhat easy to "imagine" that they make a difference.....until you know they don't.....(and I don't mean inadequate or broken wiring\/cabling, but adequate works).
