@mijostyn , you can’t build a CHANNEL based system with Atmos, 2,5,7, or whatever. Atmos is object based, different format. You don’t NEED an object based setup for music. It is just fun to have both available on your remote. I prefer channel based for acoustic jazz, folk, and strings. Object based for rock, hip hop. house, and EDM. Smooth jazz and go either way as it is both bass heavy and acoustic.
I also prefer active speakers for both formats but especially for Atmos and bass forward music.
