Amp for Martin Logan

I just purchased a set of Ascent i speakers and a Decent sub from a friend that moved up to Summits. I have a Resolution Audio Opus 21 and Cat SL1 mkii pre. I am looking for an amp under $2K. I love tube mids but don't think I can afford a tube amp that will drive the Logans. Is there any SS amps that can give me the mids and still drive the highs and bass? Or how about a tube amp in my price range? Any suggestions?
