Ok Geoff, I was being lazy and didn't bother to look up the specs, here you go, costing $15:
Choice™ Series 12AWG Oxygen-Free Pure Bare Copper Speaker Wire, 50ft. Get the most out of your home audio system with high quality, oxygen-free, pure bare copper speaker wire from Monoprice! This speaker wire features two conductors made of high purity (greater than 99.95% pure), oxygen-free bare copper. Pure Bare Copper is a superior conductor to the copper clad aluminum (CCA) conductors used in most other inexpensive speaker wire. ..
Besides, the uber expensivo cables usually aren't copper. Hel-loo!
Yes I know, silver or gold, emblazoned with magnets and graphene. With the correct directionality marked, of course, and cryoed.
