Power cable that will "calm" digital

I will be extremely surprised if a power cord will solve your problem. A much better bet is to save up and buy a better digital source. I have found there is a magical threshold in CD players above which music becomes truly involving. This seems to come with a 3.5 - 4k price tag at minimum (new retail), but mind you this translates to 2k or so on the used market. My personal favorite is the Linn Ikemi, but there are many others I am sure. Audition what you can.

Dunno if it will fix the issues you have w/digital but I just got a "Black Hole CD mat" as referenced by Listener57. It seems to make a difference to me. I am also running JPS speaker cables and CD interconnects. Did a Belkin/Marinco diy power cord as well. Recently puchased a pair of Halo 9 tube dampers for Ei 12AX7 tubes along with Tender feet for the amp (all from Herbie's Audio Lab). Things are sounding very good to me right now.

Put your digital on a seperate power cond. or Isolation transformer and you will notice a very very nice improvement

I agree with Newmanoc - a power cable is not going to resolve the issue of your digital front end sounding like "digital falseness". Don't neccessarily think you have to spend 3.5k+ (or 2k used) but you can definitely improve the smoothness of your front end. I'm extremely pleased with the tube based Musical Fidelity A5 but there are many options - also look at Cary and Resolution Audio.

FWIW, as far as cables are concerned, I even think an intereconnect change could bring more differences to sound than a power cable change.

The JPS labs digital reccomended by others has a filter network molded into the plug. Net effect seems to be a bit of isolation provided between the noisy digital equipment and the rest of the system. This can work to cut down on some of the tizz. At 200 or so list, I think markup on the cable has got to be 1000% or so, but that is audio.
