A good coat hanger is actually a damn fine wire for speaker cable. Most of what you want there is ability to handle big current spikes. I made 'audiophile style' cables using simple house cable solid-core, wrapped in opposite directions around a polystyrene tube core, so the conductors keep crossing at right angles (the point of that shenanigan).

Works fantastic. Sounds a lil' better than zip-cord, and of course at these levels it's a game of countless 'lil better' choices wherever possible.

I guess you could pay $2000 to have the conductors made out of silver and yak hair, but the 'heavier conductors and cable geometry' parts don't require any of that.
