Our Verdict

Denon Home Sound Bar 550

Samsung HW-Q900A

While the Denon Home Sound Bar 550 is a decent standalone choice for dialogue-centric content like TV shows, the Samsung HW-Q900A is the better choice overall. The Samsung is a 7.1.2 setup with a dedicated sub that can reproduce a more extended low-bass. It has better soundstage and center performances, and it gets louder with less compression at max volume. It also has more sound enhancement features, such as room correction.
