Given the audio qualities of the Thiels and Bryston, I think that the Alpha-Core Goertz MI2 Veracity (copper) speaker cables, terminated with their silver spade lugs, will provide a good match. You can buy the cables direct from Alpha-Core on a money-back, 30-day trial. Here's the link to their Web page describing the speaker cable:
