I love Bryston, but amps much better than pre amps
I use a Bryston 4B ST, and it does a great job of driving the Logans. In the past, Bryston was considered bright. This label has stuck, but is not necessarily true. The newer versions are very neutral, especially the 14 B SST, which I would take over anything nearly 1.5 times of its price range. Also, good cables take some the brightness out from the older equipment.
As for pre-amps, they are very detailed and have amazing bass, but less musical in a 2 channel setup. Their amplifiers are much better than their preamps. However, the new preamp, BP 26, is a huge improvement over the past products. I am not a big movie fan, so I cannot really comment on the 5 channel product - the SP 2. Stereophile seems to like it a lot - "Class A" - for what it's worth. The SP2 has the new 2 channel BP-26 pre-amp built into it.
