what is your take on Bryston's clipping issue?


There are a few poster testified that the Bryston 4 B SST is unstable below 4 ohm load. I am planning to mate my soon to arrive 4 B SST with the Maggies. Am I heading for disaster of disappointment?

"If you own Magnepan speakers, then you really owe it to yourself to audition them with a Bryston amp. ItÂ’s not for nothing that Magnepan has used Bryston amplification for show demos."

That's a quote from John Crossett in his review of the 4B-SST in SoundStage. He used them with Maggie 1.6's.

Regarding Tvad's comment above: I own a 4B-SST that I used with Aerial 10T's. The 4B-SST could play all day at 95dB without clipping and I know I listened with peaks in excess of 100dB with no problem. The only time I was able to get the amp to clip, and that was only for a second or two, was on a direct-to-disc Sheffield Labs recording of Dave Grusin, and I was pushing it pretty hard. With that LP I've had the same problem with other amps and speakers. Michael Kelly at Aerial recommended the 4B-ST to me at one time as a good match for his speakers. I was very impressed with how well the 4B-SST drove the 10T's. I wonder if Tvad contacted Bryston about this? Perhaps his amp's bias needed adjustment?

Since you already bought the amp you'll know soon enough if it meets your needs or not. You can always try a 14B-SST or a pair of 7B-SST monos if you've got a large room and like to listen loud. My guess is you're going to love the 4B-SST.
