Thanks, again, James. The reason I'm probing you about the sound is that now that I am running 7BSST2 amps, I've discovered something new in the Bryston sound that wasn't in the 7BSSTs, or the other Bryston amps I have had. They have always been very accurate, but we're missing somethng that until recently I had not heard in my system. I have only one component that uses tubes, and it has a kind of musicality (is that the word?) that the 7BSST2s now give me to an unprecedented degree. That tube component is a headphone amp (like the sound, but not the tubes and all that goes with them). The headphone jack on my BP 26 is excellent, but much less musical and enjoyable than the tube headphone jack I'm running. So I'm wondering if the BHA-1 is likely to have the musical sound of the Bryston squared amps?
