I'm thinking of getting a new 7.1 AV receiver, one that can use the Surr. Back channels to bi-amp the fronts instead. So, given that I currently have the fronts cabled with Cable Talk Talk 4.1, what speaker cable should I use for the second run? The same? Or am I better off using the Talk 4.1 for the treble/bass and using something else for the other? Budget is "no more than Talk 4.1". Thanks, pingu.
