I have a friend (no, not @mark) who is a serious audiophile. We were talking about some of the ridiculous prices for high ultra-high equipment. I commented about cables for speakers, and he said that there are people who will pay thousands of dollars for cables.
Not sure I understand that - after all, electrons are electrons, and I'm not sure they move slower through cheaper cables. But, then, I'm just an old geezer who wears hearing aids which I only use to listen to audiobooks so shut up.
