@treebeard1, I wanted to clarify an issue with the wire gauge in the Cardas speaker cable you mentioned earlier when discussing the 9 AWG wire in the Zavfino Prima cables. The Cardas Clear Beyond uses 8 x 10.5 AWG wires, which means that the total wire thickness at each connector is 4 x 10.5 AWG in a stereo set-up. This corresponds to an effective wire gauge that is far thicker (between 4 and 5 AWG) than 9 AWG at each connector. The Cardas Clear Reflection uses even more copper, using 12 X 11.5 AWG for each cable or 6 X 11.5 per connector.
Of course, there's a lot more going on in all these speaker cable designs than just wire gauge.
