Alan posted some recommendations a few weeks ago. IIRC it was something like 12 gauge over 25 feet, 14 gauge 10-25 feet, 16 gauge for short runs.

The 12 gauge speaker wire at my Home Depot (Toronto) turned out not to be polarized (ie no way to tell one wire from the other) which was a mega-pain. I went with 12 gauge but would probably go with 14 next time.

The idea of taking cat-5 wire and twisting all the pairs together is interesting but don't know if I'll bother right now.
