Considering the BMR Philharmonic Monitor speakers

I have a pair of CSS Audio 1-TDx monitor speaker that I like very much, but have for along time considered these Monitors.  I am hoping to run them with my Don Sachs 2 preamp and a First Watt J2 amp, with 25 wpc of Class A power.  I have other more power amps, but I really love the J2.  

I'd be keen to get any impressions from others about their sound and performance and your thoughts on amp pairings.
