I haven't tried the Classe but I am running Nemos and have had the chance to put a Plinius SA Reference from my second system.
The rest of the gear:
Audio Research Reference 5SE (Silversmith XLR to power amps)
EMM Labs XDS1 (ASI Liveline XLR)
Speaker cables (ASI Liveline speaker cables)
Thiel CS3.7s
The Nemo has amazing control of the bass but the Plinius is even more controlled. But the gain is pretty high on the Plinius so I found I couldn't dial the ARC to as high a level that I feel is optimum for the ARC.
