I've heard the regular Model T as well as the Axiom M100 which I believe they are based on (or vice versa?). They were both enjoyable, I would say a little bit relaxed sounding, nice dynamics, focus on being smooth rather than ultra detailed, so they are good for a variety of music including lower quality recordings. I did think the Bryston option was noticeably better than the Axiom despite their similarities. I don't know what they do differently, maybe superior crossovers or bracing etc but it works.
Never heard the active version so can't comment on that. My one complaint is that I don't like the finish at these prices. They aren't necessarily ugly but I would expect more when paying this much.
