Amplifier recs for Sonus Faber Cremona Auditor M?

My primary system consists of Aerial 10Ts driven by a ML 334, with a ML 38S and a ML 390S. I listen to classical, jazz, rock, instrumental, vocals, and some R&B. I have been very happy with this system but recently caught the all-too-contagious upgrade bug, and we all know where that leads . . . . So I am selling my 10Ts and replacing them with the Sonus Faber Cremona Auditor Ms and the REL R-305 sub-base system. I LOVE the SFs with the REL. I will stick with the 334 and 38S until some point after the SFs are broken in, but I already know I want to see just how good I can make the SFs sound. My $$$ limit for both amps combined is $12K; I prefer to purchase new electronics. Thanks in advance for your comments!
