Recently, I posted this over at avsforum and thought I would share it here. For anyone considering the purchase of a new amp, the following is food for thought! I have two Bryston amps -- a 4B-ST and a 9B-ST. They were purchased new in 2001. In March of last year, one of the channels failed and I brought the amp to Bryston's service office in Toronto. It was repaired and I was on my way in less than 45 minutes. I had a different channel fail late last year and brought the amp in for service again a few weeks ago. Again, it was repaired and I was on my way in less than an hour. The very next day, the same channel that was originally repaired, failed yet again. I sent an email to Bryston voicing my displeasure with the obvious problems I had been having with my 9B-ST and stated the 3 failures I had in less than a year were unacceptable. The next morning I received an email from Chris Russell (CEO of Bryston) and he agreed. He advised me to take my 9B-ST to the service office in Toronto and that he would exchange the amp for a brand new 9B-ST. I drove over the next afternoon and made the exchange. While the repairs and failures have been rather frustrating, the level of service I have received from Bryston has been outstanding. And while I have only had the new 9B-ST hooked up for the last two weeks, so far all is well - again. If there is anyone contemplating the purchase of a new amp and giving Bryston consideration, their level of service is exemplary. An amp is one of the few pieces that can be kept in our systems for a very long time. That said, the 20 year warranty should be factored in heavily, in making your decision. BTW, there seemed to be some ambiguity as to the power rating of the new 9B-SST versus the 9B-ST. The new 9B-SST power rating is IDENTICAL @120 wpc. What has changed is some circuitry and the faceplate. I can't imagine the changes being overly significant. Herb.
