It all depends on what you are driving. I have 2 Bryston amps with a CJ Tube Preamp because I need the horsepower for my B&W 801. You probably have more efficient speakers therefore the great results. Your set up probably would not work well with my speakers. You have two very nice pieces so I'm sure it can sound wonderful with the right speaker.
Conrad Johnson MV60se amp paired with Bryston
I am not an audiophile and seek your opinion. I have an older Conrad Johnson MV60se tube amp paired with a Bryston BP6 preamp. The detail and smooth sound of the tube amp appears to match well with the transparent Bryston preamp. Am I crazy or would the CJ classic tube preamp be a better match?
