Get a used pair of Acoustic Zen silver Reference two's. Currently there's a pair under 5 on Audiogon. This cable has been favorably compaired to the Nordost Valhalla. Robert Lee really knows his stuff. These will show off the detail of your Bryston amp without harsh glare. I have Classe amps and Pipedream speakers and the Ref 2 is ideal. Rca or ballanced, they perform as advertised. Do a search on Audiogon with the word zen and check out the prices. Even if you don't like them, you can unload them for what you paid for them. They're popular!
