Opinion: SF Concertos w/ Bryston 3B-ST?

Thanks for your input. I just picked up a used one last night and spent three hours with it. My first impression is for the first half of the three hours it was clean, transparent, dynamic all that good qualities people talked about Bryston amp. But I felt it was kind of "cold". Later its sound became bit "warmer". Perlman never sounded this good with mt system. I'm going to try to leave the amp on all the time after Bryston told me the amp sounds optimal after warming up (hour and half so). Later I found out the amp is really a 3B-ST PRO. Does anyone know the the difference between 3B-ST and 3B-ST PRO? Thanks. Mike

I think the Pro version gives you a ground lift switch and different cosmetics. www.bryston.ca for all thier products. I would encourage that you leave your (solid state) equipment on if possible. The only time mine gets unplugged is stormy weather. Makes for easy listening where everything is warmed up and sounding its best. Enjoy. -tw

Better off try the Krell KAV150 power amp with a tube pre-amp. Also heard it with the Plinius 8150i integrated. Either of the two, you can't go wrong.
