I agree with pkvintage, I have owned Bryston amps for the last 33 years. 3B for the last 30 years, and 3B SST2 for the last 3. The 3B SST2 has more detail and tighter bass than the 3B had, the only reason I replaced the 3B was that I just wanted to upgrade after 30 years. Bryston service is second to none, and they have a 20 year warranty that is transferable. I I expect the 3B SST2 to keep me happy for the next 30 years also. IMO you can't go wrong with Bryston.
