Hello Bavarian05,  I started out with a McIntosh MC452 and found it was way too much of a good thing with the Evos.   Sweet,  but slow and somewhat muddy,  to my taste.  I moved on to the ARC REF150 and,  to me,  it was a great match,  except for the heat it generated in my small room.  Ideally,  I would have had two amps,  the ARC and maybe my current Ayre solid state.  I think the Evos do need waking up to achieve their fullest possible beauty.  The Hegel that everyone is talking about could be a great match also,  if you could swing it.    I think it would make the Evos sing.  I know Joe is going to pair one with his Strads.
