audiphile power cords


Do upgraded power cords really make a significant difference in sound quality? I have a Jolida 502p that I think sounds pretty good. What do you recommend for a power cord that would make a significant improvement?

All you guys have to do is listen with a standard PC and try something good. You need to be deaf to not hear it. Or, I guess, if you don't hear it, your rig is not revealing enough.
I think I hear it, but have not done enough A/B comparisons to be sure. As long as it sounds as good or better to me than before, I am happy, placebo or not. I think not, but these more subtle things are hard to say with absolute certainty without extensive testing that I do not have time nor desire to do
@Rockdanny- When you have your dedicated lines installed: if using Romex, put a good twist in it, over it's entire length, to reduce noise(EMI/RFI) pickup, and to cancel the wire's own magnetic field. When I did mine; I used a double run of 10 AWG, which is the equivalent of 4 AWG. That was over 120Ft, to the room and what a difference, from the 12 AWG that was in there!
