A lot of people, and even some speaker cable companies, recommend high strand speaker cable. The idea being that high strand cable has more surface area than low strand or solid core and that this reduces resistance.

From what I gather, they are referring to "skin effect" which causes signals to travel near the surface of the wire. Therefore, more surface area = better signal. There's a couple articles, however, that say that this really only has significance at very high frequencies such as 100khz and above. And that from 20hz to 20khz skin effect doesn't really matter.

Any thoughts? Would love to hear from any enginerds out there. Maybe Dave, if you aren't too busy?
