Thanks all for the responses. I purchased the Bryston to go with some other speakers (still waiting for the bryston to be built) but I have a pair of Cornwalls boxed up in the basement that I had used with 300B and KT88 amps. I am sure that curiosity with take over and I will eventually try them together. Just alot of effort to get those boxes upstairs unpacked and put in place just to find out they cleary do not work with Bryston. It sure would be loud enouph wouldn't it.
