Lamm or OTL for Kharma CE-2.1's?

I'm ready to take the step forward from my current amps - Belles 350A Reference and Manley Snappers.

Thinking Lamm M1.2, ML1.1, Atma M60, Joule VZN-100...

The compatibility of the Lamm amps with Kharma speakers is well chronicled. Does anyone think the ML1.1 is dramatically better than the M1.2?

I'm intrigued by the reports of speed and clarity of OTL amps. Unfortunately I have never auditioned any. If you think they're better, how much better and why?

Any first person experiences comparing any of these amps?

I'll probably end up with slightly more difficult to drive speakers than the CE-2.1s, but nothing any of these couldn't handle.

Thoughts? Recommendations? Thanks, Tim
