Hi Every one in a while I get the bug to start looking at system upgrades. I was thinking about my Cable Talk 3.1 bi-wire speaker cables and if it would be worth upgrading. I'm running them out of an Arcam Alpha9 to B&W CMD 1NT speakers. Anyway, speaker cables must have progressed since I bought these (97/98 perhaps) and was wondering if an upgrade would be worth it. I was thinking of getting some thinner cables if I do go for an upgrade. Any advice?
