Our Verdict
Samsung HW-Q900A
Vizio M Series M512a-H6
Depending on your listening habits, you may prefer either the Samsung HW-Q900A or the Vizio M Series M512a-H6. The Samsung is a 7.1.2 setup with more wireless playback options and sound enhancement features, like room correction. It gets louder and has built-in voice assistant support. That said, the 5.1.2 Vizio comes with discrete satellites. It has a better soundstage performance, too.
