Balanced cables will usually be better only of the equipment you are using them with are really fully balanced designs. I'm not that familiar with your equipment, but I don't believe that Conrad Johnson manufactures any components that are fully balanced. The only other consideration would be that a balanced cable would have less signal loss over a very long run.
Are balanced interconnects usually better?
I just replaced my amp with the Bel Canto EVO 200.2 which accomodates balanced interconnects. Previously, I used MIT RCA interconnects which I probably bought for about $150.00 for the pair to connect my amp and Conrad Johnson PV12 preamp. I see that Signal Cables are very reasonably priced and favorably commented upon and I'm wondering if I should replace the unbalanced cables with Signal balanced ones? Are balanced cables usually better? Can you really tell the difference? Any thoughts?
