The Atma-Sphere MA-1 monoblocks are a great match with the Merlin speakers. I listened to Sbank's system many times when he had the Bernings and then after he switched to the Atma-Sphere. The Bernings were a nice match and are excellent amplifiers. The Atma-Sphere amps were simply better: more resolving, more complete rendering of harmonic overtones, greater bass impact and control, better soundstaging. (Note: I use Atma-Sphere MA-2 monoblocks and so clearly like what Ralph's amps do in making music.)
