I think you're confused about the dielectric properties of materials. More pertinently you haven't physically connected 'storing and releasing electrons' to 'changes the sound' and why this is audible but not measureable (in terms of the signal, not the materials properties).

The same statement applies to your hypotheses about being able to hear the materials of the cable, given they don't alter the LCR properties of the cable significantly.

So why do you disparage the group of people who believe they can hear something you can't? And get all upset about challenges to your belief system? We have the root causes of most of the world's problems here in a microcosm.
