Power for CAT preamp

I've listened to a bunch of different power cords with the CAT preamp and, for that matter, with many others. The best that I've heard--quietest, most neutral and musical--are the ESP (Essential Sound Products) Reference cords that Ken Stevens also recommends for his electronics. They're the best I've heard too.

I have heard both the original Essence and the last generation Reference. Both sound superb. I haven’t heard the less expensive MusicCords but I’ve been told by people who have that they’re real giant killers.
