What do you think about those really thick speaker cables? Do they make a difference?
You would think that would be easy to determine. Just do some blind, a-b testing. But this argument has persisted for many years. Part of the issue is that speakers don't usually have a completely equivalent set of terminals. So how do you test without putting too much time in the process. I can only say that I personally have never heard a difference, and that is not where I would invest my dollars.
