Power amps for Dynaudio C2's

I just purchased a pair of Dynaudio C2's. My system currently consists of a VSE-modded (Level 5) Sony 777ES, SAS 10A tube preamp, Empirical Audio-modded Carver ZR1600 power amp, and Ridge Street Audio MSE Gen. II IC's and SC's.

The modded Carver does well in that it has the power to drive the C2's. It also does reasonably well in the highs. It falls short in the mids, with some smearing and grain, as well as the low frequencies, which are not defined anywhere near as well as other SS amps I have heard (CJ Premier 350, Threshold T400) or even as well as the Atma-sphere MA1 Mk. 2.3 OTL's (but I didn't hear these amps on the C2's).

The store where I purchased the C2's from was using Chord electronics. The sound there was quite good. I was curious what others are using to drive these speakers. I am particularly interested in JC-1's, the Edge NL series amps, as well as the Atma-sphere OTL's (although I don't know if they would have enough juice or match well with the 4 ohm load).

I listen to mostly classical, jazz, and female vocals, with an occasional flashback of classic rock. Any and all opinions are welcome. Thanks in advance.
