Naim Mu-so review

Plenty of wireless speaker systems do a decent, musical job. But the Naim Mu-so can make a valid claim to be genuine hi-fi

There are some fine products emerging in the world of wireless speakers, but none that could really be called ‘hi-fi’ – until now.

British manufacturing stalwart Naim has thrown its hat into the ever-widening wireless speaker ring with the Mu-so. It’s an expensive piece of kit, no doubt, but it also lays claim to being as close to real hi-fi as a wireless speaker has a right to get. Not only that, but it’s beautifully built and feels like a quality piece of equipment too.

Looking good, feeling good

Naim Mu-So

Make no mistake, this is a premium, stylish piece of kit. The brushed aluminium skin (over hi-fi speaker favourite MDF) lends a touch of class to proceedings – the aluminium has a practical purpose too, acting as a heat-sink at the rear of the unit.

What wins it for us in the style-stakes, though, is the utterly gorgeous and tactile volume dial. It’s illuminated and such a pleasure to use that you’ll go out of your way to use it rather than the remote control. It’s also the Mu-so’s touchscreen interface, so as well as spinning it for volume, you can tap it for various functions – input select, pause/play, radio presets and so on. The display is clear, clean and classy, in keeping with the overall impression of the unit.

There’s a choice of grilles too, if the standard black is a little too Hoxton for you. An extra £70 will get you a replacement – there’s a choice of colours: vibrant red, deep blue and burnt orange.

The ins and outs

Naim Mu-So

Naim claims 450W of power lies under the Mu-so’s hood – and we can quite believe it. The amps are driving high-tech speakers that use DSP technology developed from Naim’s work with ultra high-end car manufacturer Bentley.

You’d expect plenty of options from such an expensive piece of kit, and Naim doesn’t disappoint. The Mu-so will accept aptX Bluetooth, AirPlay, UPnP, and Spotify Connect – and it has internet radio on board too.

If you want to go old-school and wire something in, there’s a USB port that will charge and play Apple kit, an optical input and a 3.5mm analogue in. And, if your wi-fi signal’s a bit flakey, there’s an Ethernet port too.

Naim Mu-So

If you want full-fat high-res (and you do) you’ll have to go through the Ethernet cable – wireless high-res tunes are limited to (a still mighty fine) 48kHz.

Remotely interesting

There is a remote control supplied with the Mu-so, and it’s responsive and simple enough to use. Having said that, if we weren’t going manual with the knob, we’d generally use the control app (iOS and Android) instead. It’s neat and gives you full control over your music collection across smart and NAS devices.

Yes, but how does it sound?

Naim Mu-So

The Naim Mu-so is no ‘style over substance’ fly-by-night. The power behind this unit is stunning, driving songs along with sure-footed rhythm, loads of detail and plenty of deep, rumbling bass, the like of which we haven’t experienced before from a wireless speaker. The scale of sound is huge for the size of the box – but it’s not all bombast; there’s subtle detail too and superb resolution retrieval with high-res tracks.

A minor niggle occurs when you really turn up the wick on the Mu-so, when the sound thickens up just a touch – but we’re talking really loud here, and there’s never any hardness or brightness to things. At regular volumes, it’s a beautiful, well-constructed sound that you just wouldn’t expect from a ‘wireless speaker’.

Naim Mu-so Verdict

Naim Mu-so Verdict

The Mu-so is a superb piece of kit. Naim has chucked pretty much every feature you could want from this type of unit, and made it sound superb at the same time.

It’s pricey, yes, but it really is as close to hi-fi as we can imagine this type of unit getting – suffice to say, we think it truly does look, feel and sound its price.
