All of the amps you mention are great. Classe is definately smooth, but is a tad laid back. Bryston is super strong, but lacks the rythm and can seem hard edged by comparison. As for Krell you pay a lot for an amp that has neither the refinement of the Classe nor the value of the Bryston. To add to the comments made by others I would deffinately try Sim's W-5. I have found the W-5 to be every bit as good as the Classe in finess, but not as laid back. When compared head to head with Bryston Sim has much better rythm and is more involving. Also, If you like the Sim sound and want more grunt you can always have it converted to a W-10 and purchase a second W-10. While the W-5's and 10's are basically the same amp (bridged) the 10's offer significantly more current 35amps continuous (20 in the W5).
Krell, Classe or Bryston?
I recently bought a pair of Magnepan MG 3.6rs and am looking for an amp for them. I would like monoblocks if possible. I recently heard the Classe Cam 350 monoblocks with my speakers and it sounded ok. But I've heard great things about the Bryston with Magnepans and the reputation of the Krells(?) seems intriguing. So what do the Maggie owners(and others) think? Or is there a better choice out there?
