There has been debates for years on directionality of cables on
www.audioreview.com. I just cant see how a cable made of copper, silver, or whathaveya can have a different molecular structure when the current goes one way than the other way.
I would think that teh only thing would be some kind of grounding that specifies that direction. unless there is a box like MIT has in its cables, I dont see why the directionality.
