After having had a number of Bryston components ( amps, preamps, integrated ) , I basically agree that Bryston has a neutral, tell it like it is, type of sound. IMO, the big decision for Bryston owners is the type of loudspeaker one chooses to match to their Bryston components and the acoustical properties of the room everything is going to be used in.
Some loudspeakers mimic ( say some Thiels ) the sound of Bryston equipment and that combination used in a live, undamped room, is going to come across on many recordings as somewhat lean or lacking body, IMO. Change the loudspeakers to say Vienna Acoustics and a treated room and you get a whole different perspective.
In other words , you are listening to system, a room and a recording. Bryston is excellent in what it does but it is only one part of the whole.
