dear Highend4me, as you know hi-end is like "esoteric". You "feel" sometimes the music instead to "hear" the music. I was skeptical that a power cord, was able to change the sound. It is obvious that if you listen to music while running in the house or clean the floors, you can hardly appreciate all the sound harmonics that a system can give you. I agree with you that we are talking about subtleties, but the sum of these make a system more engaging. One important gear of my system is this new Elrod cable.
