Default Conrad Johnson's Solid State Amplifier Series "Motif"-new for me:Are there any Infos?

From a guy, that have purchased a MS50, I have heard, this amps sounds like Class A solid state resp. like good sounded tube amps. Nevertheless this amps don't operate in class-A mode at the output.

What is here very special in the circuit topology?

Thank you for advices.
On the web there are no papers and detail describtions. At whole mainly private advertisements resp. auctions like ebay:

There are little information on this power amp. I guess it uses an bjt or fet LTP and a fet or mosfet VAS and a mosfet output stage based on Hitachis application note from that time.
