And with built-in Wi-Fi® and Bluetooth®, you can stream music from your phone or the web with the touch of a button.

Quality construction for amazing sound

Naim's engineers are fanatics when it comes to construction and parts quality. One tipoff is the Uniti Atom's massive power transformer (see photo). It ensures that the power supply is always smooth, stable, and noise-free. Premium Burr-Brown DACs (digital-to-analog converters) and hand-wired analog and digital circuitry contribute to Uniti's extremely accurate sound reproduction.

The front panel's 5” full-color display has a proximity sensor that wakes up on approach, and the big top-mounted volume control is a pleasure to use.

Digital convenience and analog soul

The Uniti Atom is a great way to enjoy some of the higher-quality digital music sources, such as high-res downloads from HDtracks, or TIDAL's lossless streaming service. The Atom can store up to five minutes of data, ensuring high-resolution streaming audio isn't interrupted by buffering. And the system can instantly access up to 20,000 songs from an attached USB drive to keep the music flowing.

Stream music wirelessly from your smartphone or tablet to the Uniti Atom via Bluetooth. The system includes aptX audio coding, an advanced type of Bluetooth wireless streaming that retains virtually all the detail of the audio signal it carries.

The Uniti Atom is also AirPlay-compatible for convenient wireless playback from your iPhone®, iPod touch®, iPad®, or computer running iTunes®. And with the Naim app on your Apple portable, you can use Rovi to discover new music and artists based on those you already like.

Multi-room audio with the Naim app

With Naim's free control app downloaded to your smartphone or tablet, you can make your Uniti Atom part of a Naim wireless multi-room audio system. The system uses Google Chromecast built-in transmitting through your home's Wi-Fi®. Chromecast built-in gives you access to all your favorite music services right in the Naim app, such as TIDAL, Spotify, Deezer and more.

Remotely control your Naim components through the app. Group your connected speakers so that the same song plays throughout the house, or only on certain systems. Or have every Naim component accessing a different source and playing a different song. You can also build playlists with the app, and browse thousands of internet radio stations.

Mine drives a pair of B&W 600 speakers indoors and a pair of B&W AM-1 speakers outdoors. I'm very pleased with the sound.
[ Douglas  May 04, 2019 ]
If you want to keep it British and the room is not too huge then a pair of Harbeth P3 ESRs will do nicely. An other brand to consider is Focal. I find the Klipsch and Polk offerings very bright. Detailed at the cost of warmth.

It does NOT have a USB input. Also, the BlueTooth is only for input...It will not transmit BlueTooth signals to external speakers; however, you can connect passive speakers to this device.
