Speaker pairing for Naim Nait 5i

I’m currently running a Naim Nait 5i, Rega Planar 3 turntable with Mofi turntable preamp. Digital source is an Innuos Zen mk3 streamer running through NAD M51master series Dac. My speakers are B&W CM5’s. Looking at swapping out with a used bookshelf speaker in the $800-1200 range. I’m wondering if the Focal Aria 906’s or Totem Arros would be a good match?  Other suggestions appreciated.  

the nait 5i is a rather lively sounding unit

suggest a slightly smoother warmer speaker than b&w focal or totem, all of which can be bright with solid state amplification

consider harbeth (i know 800-1200 is difficult, maybe an older model), older lower spendor kef sonus faber dynaudio... 
Naim and Focal are basically the same company, they should work together. 

Other than that I would start looking at British speakers. 
Look at the Vandersteen VLR Wood. It should be a great match to the Naim and can be found (occasionally) in your price range. New they are $1650. Here is a review:
