Our Verdict

Samsung HW-Q800A

LG S75Q

The Samsung HW-Q800A is better than the LG S75Q. They're both 3.1.2 bars with Dolby Atmos support, but the Samsung is able to reproduce a more extended low-bass, so you feel more thump and rumble in bass-heavy music and movies. It has a better soundstage, too.
