How significant is a power cord upgrade?

I was a power cord skeptic about 5-6 years ago. I still can't explain why they should affect the sound. However, I am now of the mindset that the power cords affect the sound, good or bad, more than interconnects or speaker cables do. As always, YMMV.

Mcpody is right: every cord will show an immediately audible difference and sometimes dramatically better and sometimes even worse than stock cord. Trying out several different ones is the best way to go. I use Cardas Golden and they work for my systems.

I just ordered parts for the VH Audio Flavor 2 power cord. Looking forward to hearing the differences.

Tried 3 or 4 power cords on amp, cd player, pre's , etc. . Made no difference whatsoever. Have had your good experience with speaker cables and ic's however.

This is true. However, it remains to be shown that a good-quality, inexepensive Belden cord can be bested by the megabuck cords. We're not talking rocket science here, all we're trying to do is get the AC from the wall to the component. Spending more than $50 or $60 for a power cord is for the hopelessly optimistic...
