After tinkering around with the Hi-Fi tuning fuses and discovering that they make a very substantial improvement in the sound of my speakers, I started looking around elsewhere for areas for yet more tinkering, and the subject of power cords came up. I have no experience whatsoever with power cords and was curious as to whether or not anyone at AR does, and what your conclusions might be.

I made a quick google search, and was astonished at how expensive "audiophile" cables are, and am skeptical that they're worth so many hundreds of dollars, especially since I'd have to replace at least three such cables in my system if I were to take this step.

So, do any of you have any experience with upgrading your equipment with "better" power cables, and was it worth the effort and expense?
