Stuart:
Don't really know your price range, but I have used 47 Labs OTA speaker cable and IC's with two SET based systems.
I downgraded from an Audion 300B SET amp to Bottlehead kit SET amps and their preamp, but kept the OTA cable.
It has worked well with all of my gear (vintage Pilot 232 6bq5 push/pull amp, vintage SE 6bq5 amps, etc.).
The cable kit runs $600 and will make up 3 pairs of IC's plus speaker cable (50 meters of cable is supplied).
