Advice on whether speaker upgrade is in order

Hi,

Looking for speaker advice.  I’m not super knowledgeable about gear nor do I have time/access to demo a lot of stuff.  I am still with my first pair of good speakers (B&W803Matrix2).  The signal first goes through a Velodyne DD10 subwoofer (using the sub's crossover to keep the lower registers).  I have a heavily Bryston system, and am probably not going to change that anytime soon:  All front end sources go in digital format to Bryston DAC 2, which runs to Bryston BP25 preamp, then to 7B squared monos.  System sounds pretty good, though I wonder if speakers are limiting factor, and I would like the simplicity of not having a sub.  I also can see what people mean about Bryston gear sounding a little tinny or bright at times.

If I were to evolve the system, would speakers be high on the list, and recommendations given this hardware? (I have read ATC, PMC, and Dynaudio are well matched to Bryston, but I don't know if materially better, and I can't keep up with the new entrants, Tekton, etc.)  Other thoughts on system evolution (or should I shut up and focus on music!).

Thanks

Matt
