Wilson Audio for a 1600 sq ft space

I love the design of Wilson Audio speakers and am looking to purchase a system for a 37' x 45' mostly open space living room. 

I host a lot of gatherings, from dinners to parties, so I am looking for a system that will fill the room and sound good at all volumes whether you are sitting or standing throughout the space. Doesn't have to be perfect. I'm assuming that anything will be an upgrade from my crappy ceiling built ins. I'm in my 30s and will be streaming mostly deep house, hip hop and rock from the likes of Spotify. 

I've been considering the newer Alexia 2s, the Sasha DAWs (and 2s) but also the MAXX 3 and even Grand SLAMM 2s since they seem to be heavily discounted used. I'm open to suggestions. Given the size of the room, the footprint of the speakers is not really a concern. 

Would appreciate any input you may have. 

Happy holidays. Cheers!
