Hi Jeffrey,
The Carver amps were driven by the Concert Fidelity tube based reference, a great sounding piece, and the BHK's were driven by two excellent SS preamps and a very high level Purity tube based preamp. I don't know what you mean by "alive". If you mean overall macro-dynamics, both amps are OK in that area. They both fall short in color/tonality and in image palpability. When I reviewed the Carver amps the SS Pass Labs had more liquidity and better air around individual players then the tube based Carvers. I really found nothing special about the BHK amplifier, it was quite run of the mill sounding compared to most SS amps on todays market. Neither was my cup of sonic tea. I could also speculate that some of the "the image was right on top of me" is not the room or the speakers, but the nature of the amplifier. Because you can use very low powered SET amps because of the nature of Eric's speakers have you ever tried any of these types of amplifiers? The most unpleasant I have heard the DI's sound as been when they are driven by high power SS amps, some what in your face PA system type of presentation. So easy to drive, but total conduits which expose any short coming in the upstream gear. They sounded great with excellent SS amps like Accuphase and Pass Labs XA-60.8 which sound much different then your BHK's.
