Classe Cam 350, Bryston 7bs or Sim W5


I'm looking for amps for my Magnepan MG 3.6rs. I'm considering these three amps. I need your opinions and experiences.
128x128sgr
I have the 7B's with the latest3.5R'sandfind them to be an excellent amp to drive them and not run out of juice.
Re: my Classe recommendation. I also have 3.6 Maggies. The Bryston are too crude.
