Do Cables Wear Out?

I don't know about wear out, but they can tarnish, even within the teflon (or other) sheath. I have personally witnessed this with kimber 8tc. The copper was tarnished through and through. It was a curious result. That will change the electrical properties as the adjacent conductors now have a nice green fuzz. Perhpas if one were to characterize the distortion of such a cable, it might be found to be of an even order nature, thus making everything sound nicer ;) cause even not odd is where it's at in our universe.
I am worn out of this post. eLater!

Guidocorona,
That was good. I think you need a Machina Dynamica (AKA timex watch with an orange sticker on it) lcd watch to stick on your chest of drawers thingy and just step back and watch the tarnish dissapper as the mysterious device reverses entropy.
