Ideally you should listen to any potential 'buy' with your speakers in your room, but a second best would be to listen to the 3.6's in a dealer's room. You don't mention how loudly you listen. That's a factor as a 3 db increase in loudness requires 2 times the power. I'm using a Bel Canto Evo2 and am quite happy with the results. Brian D. in Stereophile found the Classe CAM 350's to be a great match.
Good luck!
