Talk about something that's hotly debated! I was firmly in the camp that believes it can't have sonic impact, but now I'm not so sure. I'm going to try it out and see for myself. With a 60 day trial period, I have little to lose, but just became curious during the reading of this thread. You'll find a link to a power cord maker that has a good reputation, but doesn't charge an arm and a leg. To be honest, my expectations aren't that high. Then again, I have a healthy respect for some of the posters in the thread, so I'm going to keep an open mind.
