Thanks man. Most people just tell me I have a weird point of view

What you're talking about is called skin effect and there is much debate about whether it's really a problem in the audio range. 12 AWG reportedly starts experiencing skin effect a little above 4000 Hz. 24 AWG (CAT5e) is around 68 KHz. Does this make an audible difference? I don't know.
What you've done by taking multiple strands of CAT5e and twisitng them together is created Litz Wire which is a high end wire for minimizing skin effect.
Do you actually hear a big difference with your cables?
