My personal recommendation for a Power Cord would be to audition the Ensemble Megaflux FSF @ $680 6'. I switched to this from Black Mamba Power Snakes on all components and it is a truly amazing PC. I use it on a BOW Wizard CDP & VIVA Verona Monoblocks. I also use there Dynaflux FSF IC. This cable is amazing stuff and a favorite of mine. I prefered the Megaflux FSF PC to others like HT Magic, Synergistic, ESP, and other audiophiles have prefered it to the King Cobra, Electric Glide Fat Boy and others costing much more. Once the reviews begin to spill out and validate the superb quality of this cable audiophiles will be kicking themselves for ignoring it and wasting $$$. Other then that, I would also recommend the Siltech G5 Ruby Hill @ around $1800 it is more, but worth it. It has a wonderful "feel" to it (the [no sound] sound). Very good for high current also. And there is FIM's Gold Series PC.
Also consider an Ensemble ISOlink. From my experience, this will further the sonics of your already very good CDP.
Happy Listening
