Introducing Mu-so 2nd Generation

The Premium Wireless Speaker Your Music Deserves

Mu-so 2nd Generation is the successor to the multiple award-winning Mu-so wireless music system, re-engineered for class-leading performance, functionality and usability by our experts here in Salisbury, England.

Combining our 45 years of hi-fi mastery with the very latest music-streaming technology and premium design quality, this is the ultimate single-box system you and your music deserve. From up to 32bit high-resolution streaming to multiroom music to HDMI TV sound; you’ve never heard it so good from an all-in-one wireless system.

"This is the best one-box speaker system right now, making it a must-listen...A superbly implemented all-in-one that combines class-leading functionality with sparkling sound"


Tech Radar

"The previous Naim Mu-so was already considered market-leading, but the revamped amplifiers and processors, as well as the HDMI ARC addition, show that this is a company that’s able to stay ahead of the curve."

What Hi-Fi?

“We’re surprised just how much sonic progression the Naim Mu-so 2 brings…just as the best film sequels manage to add something to their franchise, the Mu-so 2nd Generation proves a worthy successor and a fine addition to the Mu-so range.”

Stuff - 5 Stars

"So how’s the upgrade? Well, suffice to say we reckon this is probably the best all-in-one wireless speaker in the world."

T3 - Best Multi-room Speaker of the Year

"Naim Mu-so 2nd Generation just crushed it. An awesome, thumping wall of sound and reliable, versatile software platform make for the perfect 21st-century music experience"


"I came away impressed by its discrete air of sonic luxury, its uncommon ease, openness, and fine detail"


"In short, there’s now no need to buy a separate soundbar and music system, as the Mu-so can do both and likely better than either you currently own."

Almost Everything Has Changed

The Naim Streaming Platform

At the heart of Mu-so 2nd Generation is Naim’s music-streaming platform, developed by 25 engineers over 3 years to offer the very best performance whether playing your own digital music collection, a world of Internet radio, or music streaming services such as TIDAL and Spotify. This acclaimed innovation is uniquely found in Naim music-streaming products, such as its Uniti range and dedicated network players, including the £20,000 flagship ND 555.

DSP - The heart of the System

The all-new multicore Digital Signal Processor (DSP) drives higher performance, providing 2000 MIPS (Million Instructions Per Second) compared to the original Mu-so’s single-core, 150MIPS DSP. You can also hear even more from your music.

We have also created a brand new limiter algorithm that keeps each of Mu-so 2nd Generation’s speaker drivers’ movement under control when at high volume levels. The new limiter, by design; is only active at extreme volume levels, and helps to retain the music’s clarity and increase long term reliability.

"We've been floored by the performance of the Mu-So 2, especially when it comes to Apple users and AirPlay 2."
Gear Patrol | Mu-so 2nd Generation & Mu-so Qb 2nd Generation | Review, Jan 2020
"The Mu-so 2 home speaker has more than 10 times the processing power of the original Mu-so, which helps it stream higher-resolution audio (up to 32bit/384kHz) and create an even bigger sound."
The ambient | Mu-so 2nd Generation & Mu-so Qb 2nd Generation, Dec 2019
"Naim has double the amount of wireless speakers Apple has in its line-up - that’s right, a whole two. But what your admittedly significant outlay buys are the products of an established, even venerable, high-end hi-fi company with more than enough expertise to blow your socks off."
Country & Town House | A Great British Brand 2020, Dec 2019
"However dark the days, people’s love for music never dims and Naim is here to make favourite tracks sound incredible on the best British hi-fi products available."

Gramophone | Mu-so 2nd Generation | Review , Sep 2019
"Not so much updated as completely reinvented, despite the similar looks, the new version of Naim's all-in-one system is an even more attractive buy"
TechHive | Mu-so 2nd Generation | Editors Choice , Sep 2019
"This speaker sounds exquisite, and it can handle any nearly any format you can think of from just about any source you can imagine: online, offline, digital, or analog. This is a great music system whether you operate it solo or as part of a multi-room audio system. I recommend it wholeheartedly."
EISA Awards 2019 | Mu-so 2nd Generation | Best All-In-One System , Aug 2019
