I have some BJ cables, they are decent cables, but they are not in the same league as Signal which, in my system, has bettered Cardas Golden Reference, Triode Wire Labs Spirits, DHLabs Silver Sonic, AQ Columbia, etc. Mind you, in other systems with different loading between components Signal may be ever so slightly worse than most of those, all but the Columbia's were very competitive, in every way other than price, Signal Audio is by far the more reasonable price wise.
I do use Goertz for speaker cables with zobels, but DeWolf, "Bound for Sound" claims that Signal Cables are the best speaker cables sold, in fact, the only commercial cables he recommends. He still slightly preferred some Home Depot cable, but he's tried cables that run thousands of dollars and Signal Cable's speaker cables are the only commercial cables he recommends. I suppose some day I ought to try his Home Depot cables, but in my system, so far, Goertz has spanked all others.
