Where to go from Odyseey Stratos monoblocks

I own a Meridian 508-20, a VK3i pre, and Mirage M3 speakers. The stratos monos have been realy nice, BUT I amlooking for: more power, greater refinement, more dynamic sound. I like the musicality of the cdp & pre I have and the range of the speakers. I simply want MORE of these things and a little more dynamics as the Mirages can be a load for an amp. I am considering Krell, Plinius, Pass, and Levinson. Any advise from previos owners would help. Thanks
