Simple question, or is it...


What exactly is an audio signal made of, and what exactly is the medium it travels through in a cable??

I don't wonder why AQ polishes their wire and of course they have a reason. 
No. It's old stuff. The reasons can be found in a marketing 101 course. The more I read about "electricity" the more satisfied i am with my basic cables.

Those links from jea48 has some very good information in them though I don't think they say what he thinks they do. I think they agree more with what you've been saying though it doesn't get into directional or sound characteristics. The signal isn't in the energy it's in the wire.
