British hi-fi specialist Naim Audio’s Mu-so wireless music system already claims a Red Dot Design Award winning design with their low and linear speaker with a curvilinear front that sits unobtrusively while also producing 450 watts of sound. Its second iteration, the aptly named Mu-so 2nd Generation, is more of the same, but better.

The Mu-so 2nd Generation arrives with the same low standing aluminum casing with a beautifully machined grill in the back and gentle wave form up front. But Naim says the exterior belies the immense changes within, noting 95% of this upgraded Mu-so has been reengineered with all-new speaker drivers and 10 times more processing power resulting in “significantly improved accuracy”.


A new touch control panel ringed by an illuminated dial with a proximity sensor adds a tactile interface to the 2nd Generation, permitting access of playback controls, favorite playlists and radio stations, Spotify resume, and multi-room functionality.

The Mu-so 2nd Generation improved innards are optimized for high-resolution streaming playback (up to 32bit/384kHz), whether the source is AirPlay 2 (including Apple Music), Spotify Connect, TIDAL, Chromecast built-in, or Internet radio. Wi-Fi connectivity has also been upgraded, with the option to use an Ethernet remaining for those keeping it old school and wired. Bluetooth and USB inputs round out all the input sources for audio playback.

And for those looking to simplify and integrate the Mu-so 2nd Generation as their primary audio source for home theater double duty will appreciate the inclusion of HDMI ARC for simplified connection between modern televisions and the audio system.

Finally, the $1,599 audio system is fronted by an updated front speaker grill styling, available in a standard black, or in more colorful options of Terracotta, Olive, or an expressive Peacock to complement the new burnished grey finish.
