Side-by-Side Comparison

	Naim Mu-so Utopia	Devialet Dione
Channel layout Counts speaker channels the bar actually has. More ear-level and height channels means a wider, taller sound field.	7.1.2	5.1.2
Height channels Drivers aimed at the ceiling, which is what makes Dolby Atmos sound overhead rather than just wide.	2	2
Dolby Atmos	Yes	Yes
DTS:X	No	No
HDMI to the TV eARC carries lossless Dolby TrueHD and Atmos from the TV; plain ARC compresses them.	eARC	eARC
HDMI inputs A spare HDMI port for a games console or disc player.	0	0
Subwoofer Included beats optional beats none: a separate subwoofer is where deep bass comes from.	Optional	Built-in
Rear speakers Real rear speakers put effects behind you; without them surround is simulated from the front.	None	None
Room correction	Yes	Yes
Streaming	Wi-Fi + AirPlay 2, Google Cast, Spotify Connect	Wi-Fi + AirPlay 2, Spotify Connect
Voice assistant Built in, rather than through a separate smart speaker.	Works with Siri and Google Home	No
Dialogue enhancement	—	Yes

Width / suits TVs from Neither is better: match the bar to your TV. See the size simulator below.	39.37 in / 50-inch	47.25 in / 55-inch
Drivers in the bar	15	17
Power (total, as published) Makers rate soundbar power differently, so the totals are not a like-for-like comparison.	720 W	950 W
Weight	31.1 lbs	26.4 lbs
List price	$6,500	$2,399

Green marks the better figure where one is better. Dashes are specs the maker does not publish.
