Some years ago, a reviewer (for Stereophile, I believe) recommended using only AC power generated by water (Hydro) power. Swore that it "improved sound quality."

Compared to getting your AC from a lightning collector a la Dr. Frankenstein, I'd have to agree with him.

Maybe it's more organic sounding - your power would throb in ebb and flow with Mother Earth.
