Van Alstine or Bryston for me?

I am looking for a new power amp for my Salk TongTower speakers. I am considering a Van Alstine Ultra 350 or a Bryston 3B-SST. These have similar power ratings and would adequaltely drive my relatively efficient speakers in my small room. But, what about sound quality? The Ultra 350 is a hybrid design with no fancy casework, while the 3B-SST is purely solid state and with a more robust chassis. Both appear to be quite innovative, built well, and widely regarded as "bang for the buck". The Bryston is a little more expensive, but there's a 20-year warranty. My main interest is how these amps sound relative to each other. Any ideas??? Thanks!
