Gene, Knowing your propensity for eBay/Amazon buyer's remorse, it would be a good idea to warn you about the cheap speaker wire. Most of it is stranded copper plated aluminum wire. The sellers don't exactly go out of their way to prominently advertise that it's aluminum cable. Buyer beware.
It's crazy how expensive wire has become. Copper may not be a precious metal, but it's making a good go at semi-precious status. I need 100 feet of 12/2 with ground to wire my sister's new walk in closet and I'm not looking forward to seeing how much the price of Romex cable has increased since my last purchase, which produced severe sticker shock. Copper cable would have been a much better investment than gold or silver in the last ten years.
