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.
