ive decided to try some new speaker cables in my system, and I’ve narrowed it down to these two. Right now I’ve got bjc 10 ga. cables and they seem fine but the bug has bitten me. I would like some opinions on these two cables. Don’t confuse me with others that are way better for half the price. I’m only interested in these two. My amp is a McIntosh MC452 and the speakers are Aerial 7t’s. Also should I bi-wire or not. Thanks.
