I've had very good results with a JPS Digital AC power cord. It's the only reasonably priced cord that I know of that is made specifically for digital gear with digital filters built into BOTH ends of the cord. It's list price is $349 and I got a demo pair for $270 from Galen Carol audio (www.gcaudio.com). Galen is a great guy to do business with. I feel that he is one of the best, if not the best dealer of high-end audio on the net. Good luck!!
