I'll chime in here as a recent convert (but not zealot) in the "power cords make a difference to the sound" camp. Over the past two months, I have gone from using all stock power cords and a Home Depot surge protector to:
PS Audio Perfect Wave AC-12 from the outlet to a PS Audio Quintet
PS Audio Perfect Wave AC-5s from the Quintet to (1) my amp (Cambridge 840A v.2) and (2) my front end (Olive Opus No.4, with digital out to a DAC Magic).
Yes, these changes improved the sound of my system. Less noise, bigger (and TALLER) soundstage. It has not been subtle.
But surprisingly, the biggest difference came when I added the AC-5 to the Olive Opus. This one sealed the deal for me; the things are expensive, unwieldy, and like electric garden hoses, but they DO make a difference, especially (in my case) when hooked up to the digital equipment.
