What power cable for DAC?


I've had my PS Audio Digital Link III for a couple weeks now. The first week I ran it off the factory power cord and it sounded quite good. I figured it could benefit from a better pc so I got a Pangea AC-14 from Audio Advisor. Now I know this isn't the greatest pc on the market, but for the price I thought I couldn't go wrong. It has made my system a lot brighter and subdued the low notes significantly. Does anyone have any suggestions for a better pc for this dac?? If it makes any difference, my Arcam integrated amp is running off a PS Audio Prelude SC pc.

I'm using a Signal Cable MagicPower Digital with my DLIII. It added clarity to the vocals and the bass got fuller but articulate at the same time.
I followed Daniel Weiss's advice regarding power cords for the DAC1 MK2 and the ADC2 I bought from him. He said use whatever you want, it won't make any difference. But what does he know.
Duaneadam, there are units that don't gain or lose much at all from upgraded paower cords. My old Cambridge IsoMagic was a case in point. Nice if it happens to you.

Other units do show a clear improvement, in soundstage and instrument separation usually, and often clarity in the highs. (Sometimes we even get what we all want, i.e. more bass, drool.) I can cite my Stellavox ST-2, my Esoteric P-10, my JAS Audio Musik 1.2 and all my Shanling players here.

Whether or not a unit does benefit from a power cord may depend on the design and quality of its power supply. I'm certainly prepared to believe that Daniel Weiss knows how to build one of those.
In all fairness, his e-mails regarding this were a few years ago and it's possible he has a different position now. I'm trying to keep an open mind about this issue until I've done my own tests which why I'm hosting a shootout-see my post.
