Across 13 features we can compare from the published specs, the Denon Home Sound Bar 550 comes out ahead on 1 and the Samsung HW-QS700F on 5. The biggest difference for movies is height: the Samsung HW-QS700F has 2 ceiling-firing channels and the Denon Home Sound Bar 550 has none. Only the Samsung HW-QS700F comes with a subwoofer, which matters when comparing the prices.
