I'm going to step in and say the only Monster Cable that's proven itself to me is for Powered Subwoofers or Digital Signal. I ran Monster Cable to all of my Surround Speakers and I can't say it gave me anything with lower bass, but I can say it did in fact have a higher upper end frequency response than solid copper.
I have no idea if the shield that Mosnter speaker wire is wrapped in really works or not.. I won't guess and say that it does..but I'm a down to Earth person and Monster gives me better sound for my system.
