Another thought, call Audio Adviser. They buy Audioquest cable in bulk. They have a guy there and all he does is terminate speaker cables for them. They call it their No Frills cables. A pair of AQ Type 8 cables, 8’ long goes for @$340. They uses several different AQ cables. I’ve been using their No Frills AQ Rocket 88 cables for a few years now and have been very happy.
Give them a call and see what they suggest. Even if you don’t buy, you might get a better idea of what’s out there.
All the best.
