The Mu-so QB is the Naim baby brother to the highly acclaimed Mu-so. It is so named as it is a far more easily locatable cube of only 22cm3.  This certainly doesn’t come at the expense of any functionality as the Mu-so Qb has all of the functionality of its larger sibling, including Internet Radio, digital streaming, TIDAL and Spotify Connect access, AirPlay and Bluetooth as well as analogue, digital and USB connections. 

Controlling the Qb is as simple as the larger Mu-so using either the Naim app or the fantastically tactile touch screen and volume dial on the top.  The IR controller is also available but now only as an optional extra at £9.99.

Naim have been particularly ingenious where it comes to producing the cabinet of the Qb, with a single piece of 20% glass-filled polymer, the same aluminium heat sink used on the Mu-so and even a single-moulded grill to go around the front three sides.  The side attached 2 x tweeters and 2 x mid-range units, each powered by a 50w class D amplifier, and 2 x passive bass radiators working alongside a whopping 100w separate bass driver.

 The Mu-so Qb should appeal to an entire range of people who are looking for high quality audio but couldn’t necessarily afford the space required of the larger Mu-so, as well as people who just want to expand their existing Naim multi-room at a cost effective way into another room.

 The Mu-so Qb costs £649 and comes with a black grill, which can be changed for a more colourful Vibrant Red, Burnt Orange or Deep Blue for a further cost of £49.95.
