Would the PSB Alpha B1 loudspeaker be a good match for my rotel RA-1520 amp.

Right now I am leaning towards the B&W 685 (as I have listened to this setup with my amp) but am hesitant due to the cost of the 685.

I am currently running Boston Accoustics T-1030 that I bought new in the mid 1990's (I think it was like $1,200 Canadian at the time for the pair) and had recently refoamed. But they take up too much space in the office.
