I'm with Marcus- try Synergistic Research and start at your digital front end. My first high end power cord was a Synergistic AC Master Coupler- IT BLEW ME AWAY. I have since gone 100% SR Tesla. These new PC's are light years ahead. It is a good idea to audition several PC"s in your system before you buy. I've also had good luck with MIT and Audience.
Which power cord more important?
I'm thinking of changing my stock power cords for my cd player and 100 wpc integrated for better ones...however, I might have enough just to change one of them for now....am I right assuming that the power cord for amplifier will make a bigger difference than the one for the cd player?
