The BP6P and the 4BSST Pro are the best equipment I've owned. And I've owned some expensive equipment. Such as the megabuck FM Acoustics (from Switzerland) I had their 611 amp, and the damn thing used to overheat on me and shut down. I've never had that problem with my 4BSST.
The Bryston sounds great, is reliable, and is built like a tank. What more do you want?
