OK, thanks for all your replies!
I found a mint condition 2B SST2 at a very reasonable price so I am thinking about buying it. 100 Watts a channel would be more than enough power for me. I am not a fan of big amplifiers because my system isn't placed in a big room and because I rarely listen to music loudly.
I also know that Bryston amplifiers typically deliver 10% or even more power than their spec-sheets suggest.
