There are substantial differences in the sound of the various
iterations of Bryston amps and you should try to get the SST2
series if you can......
even if you got a 3b, you’d have 250w into 4ohms which
would better the ARC and you should be able to get that around 2K
used.....the 4b doubles those numbers and there’s one on gon for 2900, that you should be able to get for 2500.........so you shouldn’t have to go back 3 models in series iterations to get in your price range......you should be able to get 500w plus into 4ohms and stay where you need to be with a later edition of the bryston’s with the Torus transformers etc......I ran 7bsst2’s with my very current hungry Magnepans and I now have the 28bsst2’s with those same speakers........It’s not about power.....it’s about headroom and overall control. Are your speakers controlling your amp or vice versa ?
