Our Verdict
Vizio M Series M51a-H6
Samsung HW-Q800A
Depending on your listening habits, you may prefer either the Vizio M Series M51a-H6 or the Samsung HW-Q800A. The Samsung is a better-built 3.1.2 setup with more wireless playback options and a more neutral stereo sound. It also comes with a graphic EQ to help you customize its sound. However, the 5.1 Vizio has discrete satellites and offers better surround and Dolby Atmos performance.
