I've owned the bryston 3bsst. It is a true powerhouse with an extremely powerful bottom end. I wouldn't describe it as bright or harsh at all. My problem was the bottom end was too powerful - I couldn't control it in my room. Bryston pre-amps - well that's another matter.
Maybe the 2bsst will do the job just as well for less.
