Bhouser,
I have had the same experience listening to the combination of Bryston and MLs- they simply do not mix. Bryston has incredible power, built like a tank but at times a little dry and brittle- a bit more warmth is needed. Every time I heard the Bryston and ML combination, the sound is slightly flat and dull (some listening fatigue settles in after a short period). Yet when Bryston is paired with other speakers such as B&W etc, the dynamics and presentation is there. Classe amps with their warmer sound goes a lot better. Most tube amps go well with MLs. I do not have the Pass Labs power amp but their pre-amp and can say that Pass will be a good choice in providing the power and finesse. I also believe a lot of independent recording studios do use Bryston but it is important to keep in mind that they are using active monitors (eg Mackie) which produce a very flat response and the engineers are not concerned with the "hi-fi" listening aspects that we are.
MLs need a little of that liquid quality from an amp to bring out all the harmonic richness that they are capable of.
Happy Listening.
