My primary cable company of choice is Transparent. They have a trade up program but I haven’t taken advantage of it. I’m using their power and speaker cables for my MC312 powering a pair of B&W 702 signature speakers. My signal cables for primary and secondary system (Rotel 1582 MKII powering a pair of B&W CM9’s) I’m using Audioquest cables. Both systems sound great to me. Good luck on your search and final decision
