For every improvement to an audio system there must be some type of scientific basis for the improvement. Speakers sound better because of many things, including driver design, box design, crossovers, etc, CD players and processors because of DAC's, even amplifiers (big debate) due to power supplies and capacitors and board architecture. I'll even go so far as to say there is some evidence for anti-vibration tweaks. This makes sense and it is logical.
So if one power cord sounds better than another one, there must be a scientific reason for it. It's not just black magic or the hand of god.
Never knock something till you try it.
Well HELLO, I'd like to try it, but since you won't give me/us the company name, I CAN'T!
