About the Naim Atom Uniti HE

Uniti Atom Headphone Edition is a headphone-optimized version of the award-winning Uniti Atom music streaming system, designed to be the ultimate all-in-one listening source. Unlike traditional headphone amplifiers and DACs, which require a separate computer or streaming device, Uniti Atom Headphone Edition is a fully formed streaming system: just add headphones. It is also a superb streaming pre-amplifier: simply add a power amp and speakers, or active speakers. Uniti Atom Headphone Edition is fully re-engineered to offer the optimal personal listening performance. Using trickle-down technology from its flagship Statement amplifier, Naim has engineered a new discrete headphone amplifier, capable of powering even the most premium headphones with ease, via your choice of 6.35mm jack, Balanced XLR, or Pentaconn outputs.

No disturbance, no distractions, no compromises. City office, home study, living or bedrooms, enjoy your music, at your volume — exactly how it’s supposed to be heard. Transform any space into your own audio cocoon, lovingly crafted by the British leaders in high-end sound. Then simply escape to your exclusive world, where music, radio, and podcasts have never sounded so good.


Streaming & Bluetooth ConnectivityThe Uniti Atom is able to stream from all your favorite music streaming services. Spotify, Tidal, and Qobuz are directly integrated into the amplifier, as well as internet radio and a curated collection of HD stations and podcasts. AirPlay 2 support, Chromecast built-in, and Roon Ready status add even more streaming options, while analog and digital inputs mean you can connect many other sources too — including turntables. USB input supports playback from storage and flash drives. Bluetooth connectivity also allows you to connect to even more devices to stream your favorite music. Utilizing the aptX HD codec, the Uniti Atom is able to stream high-resolution music files effortlessly via Bluetooth (more information on wireless sample and bit rates below). It’s an incredible amount of options for one device.

How will you listen to your music?

Storage There are two USB Type-A ports on this device. One on the back and one on the front of the device. For these, you can hook up a thumb drive or an external hard drive (HD) to play your audio collection right off your drive.If using network storage you can select these under the “server section” in the Naim mobile App. This app is available via IOS and Andriod devices and this unit will work with any UPnP (Universal Plug n Play) type of audio server. If you have a large CD collection and want a great UPnP server for your home, you can pick up the Naim Core. The Naim core also works in the same App as your Uniti Atom Headphone Edition making it easy to use both devices together.Concerning the Uniti Core: when you format a drive on the Core it creates a path that only the device that created it can read. This means that if you burn a disc with the Core that the device itself can only be used to store and play that music once ripped. Also, none of the Naim streamers can play music from a device (phone, iPad, tablet, computer) connected to the USB port in the front or the back. The USB port is for external storage options only, not for USB audio playback.
