Hi guys,
Bryston has been updating/upgrading/evolving their SST series amps all of last year. From Jan 09 most of their power amps go SST 2. The amps look identical from the outside but have a small 2 after the SST on the rear panel.
The 4B that i have is from the new squared series. I had a problem with my amp in July 08 and got this replacement in sept 08 and i was sure as hell it sounded different. Spoke to a few guys and it was more a joke amongst friends as they felt i was hearing things. Finally i heard from Bryston and from the mail i am listing the changes incorporated.
1) New power supply transformer design
2)New push on/ off power switch (Thank god for this as the sensitive membrane switch had a mind of its own!)
3)New Chassis design
4)New soft start circuit(very sensitive to voltage fluctuations but can be adjusted by a simple preset)
5)New balanced input stage
6)New power supply board
7)Bridging mode performance improvement
8)Reduced point to point wiring
9)Reduced circuit board count
10)Re designed output chokes
Price of the amps remain unchanged and in case of the 4B the amp goes squared from serial No 4288(thank god that mine is SST2). All these improvements are trickling down from the 28 B SST which is considered to be a brilliant power amp for larger applications.
Hope this helps.
