What Speakers to use with my cj prmier 11a

I am running a premier 11a with a linn genki cd player and a not yet recieved premier 14 pre. currently running a pv10al and proac 1sc speakers. I am happy with the over all balance of the linn/pv10al/prem11a/1sc system and at this time have no analog head. but my room size is increasing and I am considering a pair of proac 2.5s has anyone heard 2.5s with an 11a or have any other suggestions I listen to a lot of types of music but my soul lives for the rythem section. this may sound odd considering my choice of amplifacation but I find the combo works with the overall balance, and I do listen to and live for that overall balance. I love the warmth detail and subtle nuances of this system. Would earlier proac 3s 3.5s 1.5 d15s d2.5 or what have you be a better choice. I do like the sound of the 1sc even if they may not be the last word in acuracy. Any feed back would be greatly apriciated.
