I guess this would be as good a place to ask as any - speaker cable is just really thick instrument cable, right? (seeing as how both are unbalanced TS, I can't imagine what other difference there would be)
Hmm, cool, thank you! Not exactly sure what a "conductor" is if you can have variations in their amount within cables that are all TS, but I guess I'll just leave well enough alone and use each for its purpose (I think I can handle a little blind faith when it comes to protecting thousands of dollars of gear!)
