For all the nay sayers of upgrading cables, using power re-generators, and dedicated power circuits, think the process through. ALL AC voltages have noise and harmonics, which gets induced to any electrical component near by. So buying high quality cables which shield the radiation of this noise will help reduce the overall noise floor of the surrounding components. Re-generators take the power and completely remakes it to a pure sine wave 60Hz 120 VAC for the U.S.. Using dedicated power circuits removes all the possible external devices such as fans, transformers, and all the other crap we have plugged into our households, however due to the common neutral ground configuration this is only a minor improvement overall.
Also, I would great suggest using a power regenerator, taking your house AC and completely "regenerating" and removing all the harmonics and noise in it.
I have used a PS Audio re-generator, which made incredible improvement "removing" noise, it didn't change the sound, it made the sound cleaner and have more clarity. I also replaced all my power cables with well made high shielding AC cables to block any noise that each component might generate from their power supplies.
These 2 upgrades made significant improvements in the clarity of my music and enjoyment.
