I've enjoyed this thread. Folks tend to not want to believe a power cord can make a difference. The cord takes away what shouldn't be there, thus giving you the sound you should be hearing. And it's hard to convince others that power cords work until you make them listen. I did a simple experiment with my friend. He could hear some of the noise floor I have in my home theater set up. I had him listen near one of the speakers to see if he could notice a difference. I powered everything off and swapped out the stock cord on a NAD T163 digital pre/pro and replaced it with a DH Lab Power AC Plus cord. Turned everything back on while he was up front. He asked me a minute or so later when I was going to switch it back on.

Much to his surprise he was hearing the difference - a signficantly reduced noise floor. We tried some music and movies and the bass was taut, mid-range was nice and full. Things were dynamic. Well worth the price.
So if you're on the fence and think that power cords are bogus, I say try it first. If it doesn't make a difference to you then return it and go back to enjoying your music. But for those that have found a difference, smile and enjoy.
