I have had Plinius amps. I have heard Bryston amps (but never owned one). Plinius amps (besides the SA102 and SA250mk4) tend to sound a little dark for me. Especially in the upper frequencies. The Plinius midrange is very nice and a little warm. The Bryston sound I have heard is a pretty clean but a bit sterile. I have always considered that a lot of the Bryston sound comes from professional amp design which stresses clean and powerfuk but sterile sound. I am sure this varied from amp to amp in their product line.
So I would recommend Plinius. Only because I made that same choice abour 4 years ago, and did not regret it until I changed speakers and needed to get a different amp to match my Mahlers (I went for Amggie 3.6's which Plinius amps sound great driving).
