Holy cow! Now that is a bunch of garbage. If my understanding is correct, electrons barely even move much when in an AC signal so this might not have any real relevance to what happens. Plus I don't think there is enough current to really burn anything in at all. Last time I had my sytem cranks my cables were cool to the touch.

The one I really enjoy hearing is the directionality of cables carrying AC signals, HA!

Newcomers to this hobby must be careful where they step as to avoid the BS.
