Speakers for Bryston pre/power amp

I'm looking for 8ohm "easy to drive" speakers for recent Bryston order 135w amp+pre.
Currently have(put up for sale)PSB Synchrony one's but had problems with inexplicible loss of power & dynamics somewhere in my setup.
Just sold M6i integrated expecting better performace w/separates.
Considering Joseph Audio 25's or B&W 804D
Anyone have good results with Bryston & efficient speakers?
Deep bass+neutral performance.
