Stay tuned--I am interviewing some electrons next week and will discuss this with them.
Look, if YOU hear a difference, it is there. If YOU do not hear a difference, why worry about something this silly?
Last I checked, it is all about the music. I promise you that YOUR ROOM is a million times more important for what you hear than some stray electrons, which, I might add, fill the atmosphere along with alpha, beta, and gamma rays, among tons of other stuff.
Work on finding the best possible room modifications and forget all the cable stupidity. It is, was, and always will be bull regardless of all the oscilloscopes in the world. Oh, probably stay away from 28 gauge Radio Shack wires for speakers. It is ugly.
