Agree with proof of concept. Personally, I have found premium cables to provide blacker backgrounds and quieter quiet parts between the notes. Overall as improvement. But I also feel that there are economies of scale. I started out my power cord journey from stock cables to Shunyata Venoms. Then I upgraded to Deltas. I think that is going to be it for me. The incremental benefit of a further upgrade combined with my hearing, components and room make me feel like I have hit the sweet spot already. Ad in there my PS Audio power regenerators and dedicated 20amp lines from my breaker box and I am good. My systems are quiet, black with good resolution. I noticed the difference initially going from stock to Venoms. I feel that it is real.

I certainly have, personally, experienced the improvement power cords can make on amplifiers...how about their value on other items, such as preamps with external powersuppies, and phono preamps....I know better than to apply layperson logic, which doesn't always work in audio, but it would seem that items that draw less "juice" would be less prone to changes in power cords....thoughts welcomed, but experience more interesting to me.....thanks
