Help me avoid sonos, please

Doing a kitchen remodel and have the opportunity to do built in speakers.  I only care about the 2 speakers I’ll have in the kitchen and potentially running 2 more to our deck.  I’d like to use Google Assistant to basically run Spotify.  

I’d like to be $500-$800.  

Would love any advice to get me decent sound.

thanks to anyone that can help me out!!!
