Hello, Straits. Welcome.
I'm not sure which straits you view, but if it is that of Juan de Fuca, we may be neighbors.
Most people around here think that, of similar gauge, copper is copper. Spools of 12/2 wire from places like PartsExpress and Blue Jeans Cable are pretty popular. Some people claim to be able to hear a difference with esoteric cables, and I am happy for them. I am quite certain that I would neither be able to discern a difference, nor place requisite value upon boutique speaker cable. Spending more money often does get you more flexible or attractive cable, however.
