Naim Uniti Atom Headphone Edition

Naim Audio Uniti Atom Headphone Edition.

What we Say:

The Naim Uniti Atom Headphone is a brand new product from Naim Audio.

Naim have taken all the features of the Atom and turned it into a great streaming headphone amp and pre-amplifier. It will work well as a standalone headphone amp or streaming pre-amplifier. If you want to run a pair of loudspeakers you have two options. Add a power amplifier and passive speakers or add a pair of active speakers.

The atom Headphone edition has balanced outputs so works really well with active speakers such as ATC SCM19A or 40A. The performance of the Headphone edition is much improved over the standard Atom. This Atom headphone edition retains most of the other Atom features apart from the HDMI ARC connection.

The atom is designed to drive even the most demanding headphone loads. It will help you realise the performance of whatever headphones you have. There are 3 different connections for your headphones. There is a standard 6.3mm jack for single ended connection. For balanced connection there are two options, the first is a 4 pin XLR socket and the second is a 4.4mm Pentaconn connection.

Uniti Atom Headphone Edition

Relax at home, without distractions

The Uniti Atom Headphone Edition can transform any space into your own audio cocoon. Where typical headphone amplifiers demand tethering to a computer the Uniti Atom Headphone Edition has all the brains – and Naim’s exclusive streaming platform. The headphone-optimised version of the multi-award-wining Uniti Atom also features Balanced 4-pin XLR and 4.4mm (Pentaconn) outputs; 6.3mm output, plus is compatible with an array of headphones – we suggest Focal as the perfect partner. Offering yet more flexibility, you can keep up to three headphones plugged in and switch sets depending on what you’re listening to and when.

Stream your own digital music library, favourite radio stations and podcasts, and music from Spotify, Apple Music, Tidal and Qobuz through your headphones without life disturbing you. Also wirelessly stream direct from all your devices via Apple AirPlay 2 and Chromecast built-in, plus connect other sources, from turntables to USB drives. Explore and curate all these choices via the Naim App.

For when you want to listen out loud, it also excels as a compact streaming pre-amplifier. Just add active speakers, or a power amplifier and speakers – for an instant system.
