I would say that dry is an accurate term for the β22. Not overly dry, but I even mentioned it sounds somewhat dry compared to the Krell in post #129. But I would qualify dry as neutral, so I think we're saying the same thing, it's just that I see dry in the middle of the spectrum, and edgy to the left. In either case the more time I spend listening to the Krell, the more I fall in love with it. It really is a superb amp for the K1000, and probably a superb amp period. I don't have speakers worthy of testing that at the moment. At this point it's doing everything right. As I said before bass is not quite as deep as the β22, but I'm talking negligible amounts here. Are you sure you really want it back?
As for the box with the work project... send away, I'm game. Also could you send the passive pre-amps? I want to give them a try.
