Power cable that will "calm" digital

JPS Digital AC-had one for audition from the Cable Company

If you can find a modestly priced power cable of an older edition from Marigoaudio.com, then this may help by removing the digital nasties, as it did for me.
Also, vibration control with Herbiesaudiolab.com "The Black Hole" CD mat will help, for a ridiculously low price of $4.49, not a misprint!
This minimalist mat design represents the single best value to be found in entire Kingdom of Digital Tweakdom.

Look into JPS Labs cables. They worked wonders in my system - created a more open natural sound and eliminated digital nasties. Check our their website and reviews. I can't recommend them highly enough. And, buy used if you can.

I personnaly use Cardas Golden Ref on my system and am very pleased with the results. However my local Naim dealer uses Harmonic Technology and his system sound very good and he is on the outskirts of town and I would think his power may not be the best there.
