Best speakers for Canary Audio CA-301CA


I have a pair of B&W 683 (90db sens) being run by Canary Audio CA-301 AE (24 watt 300B push pull) with Canary C630 preamp.  I love the warm tube sound and timbre midrange, but considering a better matched speaker for this set up.  Any suggestions?

Room size, musical tastes? 
21x22x12.....like acoustic singer song writer....though prefer all types.

Have just spotted the new Klipsch Forte III, would imagine these would really shine attached to the Canary tube Pre and Amp?
