The headphone Edition of the Uniti Atom was surely one of the most frustrating new products of 2021, the other being the Naim Solstice.

As with Solstice, utterly brilliant.

And almost completely unobtainable.

Finally, about six months later, Atom HE is starting to flow through again. It might be intended as primarily a headphone amp / streamer but it’s also a very impressive streamer / preamp with both balanced and single ended outputs. So far, the (few) lucky buyers have mainly been partnering it in this way.

Cut and pasted spiel:

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.

“Whatever you choose to play through it, the Uniti Atom Headphone Edition never ceases to delight”
