Speakers For A Mini System

I want to buy a one unit mini system for another room in my house. I am considering an Arcam Solo or Solo Mini, a Cambridge Audio One or NAD C715. I do not want separate components for this space, not even an integrated and CDP. I am looking for some advice on what type of speaker to pair with such a system, as I have no experience whatsoever with mini systems. I'm looking to spend about $400 used on the speakers. One thought that I had was Totem Mites or Dreamcatchers, might they work? BTW, I have read positive reviews of the Denon D M37 which includes its own speakers. Has anyone actually hard this system?
