Naim Mu-So 2nd Generation Wireless Speaker System

The Naim Mu-so 2nd Generation Wireless Speaker System is a premium wireless speaker, a successor to the award-winning Mu-so wireless speaker, packed with multiple network capabilities for multi-room, streaming with Spotify, AirPlay and more, as well as 32-bit audio and HDMI connection for a quality musical experience.

The Mu-so 2nd Generation uses Naim’s custom developed music streaming platform, found in other Naim products such as their Uniti series, and offer the best performance when playing digital music. Easily stream music from music apps such as Spotify and Amazon Music, and even Hi-res services such as TIDAL. The new multi-core Digital Signal Processor produces a higher performance over the previous model. 2000 Million Instructions Per Second allow you to hear even more from your music than the original Mu-so’s single core 150 MIPS DSP. Musical clarity is maintained even at high sound levels with a brand new limiter algorithm to keep the Mu-so’s speaker momentum under control.

The 2nd generation Mu-so is full of networking features, allowing you to play music through the wireless speaker from virtually any source. Compatible streaming services include Spotify and TIDAL, and AirPlay 2 lets you play music directly from your iOS device. The Mu-so is Roon Ready, so you can browse all you digital music in a neat, easily-navigable library to streamline your choices. With Chromecast and Bluetooth built-in, the Mu-so can play music from any music streaming service you want to use, including supported Chromecast supported Deezer, Qobuz and TuneIn internet radio.

With 450 watts of power, the Mu-so drives optimised speaker drivers, developed jointly by Naim and Focal R&D department, to perfect speaker precision and performance. The new intuitive dial on the top panel of the Mu-so has 15 touch sensitive buttons in an illuminated dial that also has a proximity sensor that wakes up the display. Control the features of the Mu-so including multi-room, Bluetooth pairing, input switching and see connections to Chromecast, Spotify Connect and AirPlay.

Featuring a HDMI input, the Mu-so is able to improve your TV sound so you can enjoy your favourite shows and movies with quality sound. An optical input is also available for digital sources, as well as a 3.5mm jack for analogue audio.

Multi-room is made easy with the Mu-so wireless speaker, either combine it with other Naim networked products, including the 1st generation Mu-so and Mu-so Qb through the Naim app. Easily control your Naim speakers and music and enjoy whole-home audio. The Mu-so 2nd gen can also be paired with other Apple AirPlay 2 compatible devices, through the Apple Home app, or by pairing with Chromecast devices, controlled by the Google Home app. The Mu-so offers many options to create a seamless multi-room setup for you to experience music throughout your house.

In a premium aluminium casing, the Mu-so shares its design with its predecessor, but is 95% re-engineered with upgraded components and a new cabinet design with 13% more internal volume to create bigger, deeper bass. With internal bracing and baffle moulding, unwanted vibrations are supressed. The Naim Mu-so 2nd gen wireless speaker has a style update, with three new grilles available separately in Olive green, Terracotta red and Peacock blue, to customise the Mu-so to your décor. A black grille is supplied as standard.
