For those who have been following the comments on this thread, Marc Mickelson has posted a follow-up and summation to his reviews of the CAT JL2 and Atma-Sphere MA-2 amplifiers. His comments in part:

But even with all of the praise I hefted on the JL2 Signature Mk 2, if I had to pick a single amplifier as my favorite, even among the many truly great amps that I've heard, it would be the latest version of Ralph Karsten's OTL powerhouse, the MA-2 Mk III monoblock ($32,800 per pair). The transparency of its midrange was dramatic and involving to my ears in a way that the sound of no other amp is, and its lightning-quick attack never came at the price of hardness or etch. "Unforced resolution" is how I summed things up, "the earmark of the highest performance high-end audio has to offer."Two outstanding examples of the skills of two excellent designers. (N.B.: I own Atma-Sphere MA-2 amps and love what they do with Avalon Acoustic Eidolon speakers.)
...
If I ever have a spare $33,000, I will be sending it to Ralph Karsten for a pair of his MA-2 Mk IIIs. In the meantime, the CAT JL2 Signature Mk 2 is more within a dreamer's reach and an amplifier that I will bet can drive even the most uncooperative speakers. With either amp, you get a lot of memorable music for your dwindling dollars.
