Best Speakers for small room under $3.5k

Why do you need to upgrade??? You have a great pair of speakers now! Yeah, you can get different sound, but better? Assuming the B & W's are fed enough current(which your Bryston 3b-st is DEFINITELY doing), they make wonderful music. Just like in your thread about your disappointment in the new DAC, I think you will feel a lot of regret in the end. That being said, speakers I like(in addition to B & W) are Coincident, PSB, Soliloquy, Triangle, and Vandersteen. But, I can't say any of them will make you happier(unless you are looking for a speaker with more bass).

Outliar. What is it about the sound that you would like to improve or change? I agree with Trelja, you have a very nice set of speakers. You may also want to be certain that you have exhausted your placement options before you switch to something else. Moving a speaker an inch or so can make a dramatic difference in the total sound. That's why I used the word "exhausted" - it is exhausting to fine tune a set of speakers. I recently auditined the Solioquy line and found them to be to my liking and hope to take a listen to the small Coincident Triumph Sig. Have you considered adding a powered sub or home auditioning another amp/preamp or integrated (like the plinius)? These options would be well within your budget and would deifinatly give you a different sound.
