Good quality wireless, active speakers ??

Decide how much you want to spend then look at the room size. The great thing about active dsp speakers is they sound consistent so if you like them in the shop you'll probably like them at home.

Ditto for the KEF LS50 Wireless!

I bought a pair for a new house, after hearing them at a friend's house, for such a small speaker, they sounded awesome!  With their wifi capabilities, they are a "speaker" when my wife streams Spotify to them, and they are a Roon end point for my high end audio system.

I see they have a new version of the LS50 Wireless, you'll probably be able to snag the old version for a good price!  From what I see, they've replaced the DAC to one which decodes MQA and you won't need to connect Left & RIght speakers via an ethernet cable in the new version.

This is in my wheelhouse. I have Sonos stuff which I am now selling for the same reason. Just not enough sound quality and so many more options now, but many are still cumbersome. 

The KEF LS50 (newest model if can afford) is a great pick. I just got a used older model (was just over 1k used) which is really a nice pair of speakers. Dynaudio also makes some wifi active speakers which I think need a special box however to use over wifi. 

I have some audioengines which are bluetooth but sound better than the Sonos. My favorite little bluetooth (not wifi) speaker around $500 is the Vantoo line. But not wifi like Sonos.  

I'll stop here as there are a host of ways to stream wirelessly in a house w.o. special wifi or active speakers but do require more specific gear.
