Bryston Preamps - What do they sound like?

Are you looking for the music to get through

or manhandled by a mythic "sound?"

My BP-6 was the closest thing to “straight wire with gain” I’ve heard — it simply passes through whatever it’s fed with no editorializing.  

+1 soix! I have a Bryston .5 in my collection. Transparent to the source is a good description. A clear window on the recording. That is how a preamp should perform! A "warm" sound is not accurate!
