Speaker recommendation for SET tube amp MASTERSOUND


For over a year I've been contemplating a SET tube amplifier for my Sonus Faber Elipsa SE.
I know SET is a poor match for a relatively inefficient and difficult to drive speakers, nonetheless I was completely entranced by this amp. 
 I finally got a Mastersound Compact 845. The sound is truly magical, even at low levels, and considerably different from my Mcintosh mc452/ c2600 combo. 
I'm reluctant to test the limits of this amp due to the fear of over driving the amp and damaging both the amp and speakers. I haven't moved the volume dial past 11 o'clock. I listen to classical music, mostly piano and symphony. So far just solo piano nothing dynamic. I've been listening to this amp religiously 2-3hr a day since I got it. I wasn't compelled to turn on my MAC even once since I got MS. 

I know I need efficient and easy to drive speakers to really enjoy this amp. I prefer speakers that look modern and attractive, ie sonus faber style. Ill set it up in my bedroom which is 18'x14ft with vaulted ceilings ~12'. Alternatively my office with 16'x11' with 8' ceilings.  Ill be using blue sound to stream Tidal. What would match well with this amp? Regardless of price, what would be best for my music choice? I know this is a backwards way of setting up a system, but I absolutely wanted Mastersound and nothing else. I would like to stress one more time, aesthetics are very important due to WAF. These could be monitors or floor standing. Here are the specs for Mastersound Compact 845:

I'll second analogluvr about Ref 3A.  I have a pair of Ref 3A de Capos i have used with 30wpc Primaluna PL2 and currently a 4 watt Decware.  Even with just 4 watts it still gets loud enough.  It is detailed and but rich. decent bass for a standmount
