The sub choices you listed are both solid. I own 2 svs and have heard very good things about the rythmik. As far as in walls, I am very intrigued by the offerings from Golden Ear Technologies. If I were doing in walls, they would be on my short list. I am a big fan of sonos for multi zones. I have 4 myself. Very easy to set up, excellent gui for android and ios, you can access your library or multiple free and subscription music services. You can play Bach on the patio and ac/dc in the garage or combine zones. All you need is one internet connection, everything else is wireless. To me, sonos is a no brainier.
