I extensively auditioned the Bryston 4B-SST2 to go with my new Magnepan 3.6s at the Maggie dealer.
I am very happy with my choice.
The Pass are beautiful, but expensive, and they use a lot of electricity (class A) and thus are real ovens.
I like to leave my amp on24/7 and the Bryston is just warm, not hot at all. And it sounds great.
