Our Verdict
Samsung HW-Q950A
Devialet Dione
The Samsung HW-Q950A is better for most uses than the Devialet Dione. These bars have very different designs, as the Devialet is a standalone bar that's meant for use on its own, while the Samsung comes with satellites and a dedicated subwoofer included. The Samsung has better surround and soundstage performances, as well as more sound enhancement features to customize its sound. Unlike the Devialet, there's DTS support as well as HDMI In ports for video passthrough. It's a better value, too, but if you don't have space for all the add-ons, the standalone Devialet may be more suitable.
