Actually I did. I agree that power cords make a difference because I had first hand experience. I bought some beefy power cords and the sound becomes noticeably better - the soundstage becomes more stable, better separation, and the mass string which used to sound a bit harsh now quite a bit smoother. I think you need some good system to tell the difference though. I used to have some crappy system and it's was hard for me to distinguish the sound with different component but my system now is a lot better so it's easier to tell.
I was asking if anybody had a good well thought out explanation? I have my own interpretation.
You can look at this both ways. The power cord is the last 3 feet of wire going to the power supply, or it's the first 3 feet that the power supply sees. Before, I would have said the former. But now I tend to agree more with the latter.
