Science or snake oil. The jury remains out on esoteric power cables. Ever wonder why the likes of manufacturers such as Krell, Pass Labs, Levinson and others, do not supply esoteric power cords? Makes one wonder in a way. After all what those products cost and few dollars more is of zero consequence to provide a power cable,other than what is usually supplied. Although I use aftermarket power cords myself for amp,preamp and CDP. For me where I live is more of self survival. Seeing as Florida Power & Light continue to struggle with their service after the hurricanes of 2004, and 2005. Power cords I have used is DH Labs, Audioquest,PS Audio and Shunyata. And at times have returned to the cable that came with the unit.
I think to get a good idea of what a power cable is faced with, we need to visit the Nelson Pass white paper on Power Supplies. link below.

In this paper we see the end delivery and what the power cable is actually faced with in certain amplifiers and the components used in those products, such as transformers, capacitors,etc. Interesting reading at the very least.
