A Whole System in One Box, With a Five-Inch Window Into It

The Uniti Atom is a streamer, a DAC, a preamplifier and a 40-watt Class AB power amplifier in a single case. The front is dominated by a five-inch color screen that shows artwork rather than a row of characters. The remote works on two-way Zigbee radio, so it needs no line of sight.

Streaming runs over Wi-Fi or Ethernet: AirPlay 2, Chromecast, Spotify Connect, TIDAL, Qobuz, internet radio and UPnP. It is Roon Ready, and Bluetooth 4.2 covers a phone that is not on your network.

It Will Take Your Television Too

An HDMI ARC input takes TV sound over the cable the TV already uses. Two optical inputs and a coaxial input handle disc players and set-top boxes, with one stereo RCA input for analog. USB takes a drive of your own files, and a 3.5mm jack takes headphones.

What It Will Play, and What the Amplifier Does

WAV runs to 32-bit and 384kHz. FLAC, AIFF and ALAC reach 24-bit and 384kHz, and DSD64 and DSD128 both play. Over USB the range is 44.1kHz to 384kHz at 16 or 24 bits, S/PDIF covers 32kHz to 192kHz, and optical stops at 24-bit 96kHz.

Forty Watts Means the Speakers Matter

The amplifier is rated 40 watts per channel into 8 ohms at 0.1% THD+N, in Class AB. That will drive a sensitive standmount pair to satisfying levels in a normal room, but large, inefficient floorstanders are a stretch. The speaker terminals take banana plugs, so heavy spade-terminated cable may not fit.

What Reviewers Are Saying

Rob Boffard scored the Atom 4.8 out of 5 for The Master Switch in March 2020, with an Editor's Choice award. "Every song we put through it felt bright, lively, and exciting," he wrote.

Steve Huff of HiFi Huff lived with one in June 2020 and found the Naim character intact: "the sound is rich, full, fluid, even handed, clear and clean, detailed, big and oh so so sweet," with "flowing effortless musical grace."

Who Is This Integrated Amplifier Best For?

You want one box and no separates — streamer, DAC, preamp and power amp, controlled from one app and one remote
Your speakers are efficient standmounts — 40 Class AB watts is a good match for a sensitive pair in a normal room
You use Roon, or you want to — the Atom is Roon Ready, alongside AirPlay 2, Chromecast and Spotify Connect
The television is part of the system — HDMI ARC brings TV sound in without adding a receiver
If you have a turntable or other analog sources, count the inputs first — there is one stereo RCA input and no phono stage, so a turntable needs a phono preamplifier

How Does It Connect to Your System?

Speakers go to the binding posts on the back, banana plugs first. Put the Atom on your network over Ethernet or Wi-Fi, then finish setup in the Focal & Naim app, where you also sign in to TIDAL, Qobuz and internet radio. A subwoofer or a power amplifier takes the single RCA output.

Pairs Well With

Frequently Asked Questions

How much power does the Uniti Atom deliver?

40 watts per channel into 8 ohms at 0.1% THD+N, from a Class AB output stage. Pair it with efficient speakers rather than large, hard-to-drive floorstanders.

Is this the same as the Uniti Atom Headphone Edition?

This model drives loudspeakers. The Headphone Edition has no speaker outputs at all and is built around a discrete headphone amplifier with balanced connections.

Can I connect a turntable?

Through a separate phono preamplifier. Bear in mind that the pair will occupy the Atom's only analog connection.

What is the highest resolution it will play?

WAV up to 32-bit 384kHz, FLAC, AIFF or ALAC up to 24-bit 384kHz, and DSD64 and DSD128. The wired inputs top out lower: 384kHz over USB, 192kHz over S/PDIF and 96kHz over optical.

What comes in the box?

The Atom, the Zigbee remote control, and a Naim PowerLine Lite mains cable.

What warranty does it carry?

Naim covers the Uniti Atom for two years on parts and labor, starting from the original purchase.

Best Premium Streaming Amp 2024 - What Hi-fi?

"The talented Uniti Atom is everything we've come to expect from Naim. A superb blend of lifestyle product and premium hi-fi – as it's consecutive What Hi-Fi? Awards every year since 2017 go to show. The superb Sonus Faber Omnia and the excellent Naim Mu-so 2 are fantastic alternatives, but for our money, the Uniti Atom remains the finest premium streaming amp you'll find today."

- Becky Roberts, What Hi-fi?, March 14, 2024

WIRED Magazine's 19 Delightful Gifts for Music Lovers and Audiophiles

"The bookshelf-ready Atom can play high-res digital audio files from any source on your Wi-Fi network. If your loved one already has other Naim hardware in their home, the Atom will connect to those systems for a big, multiroom audio party. But even on it's own, it sounds absolutely incredible, with a pristine-sounding 40-watt amp that will drive whatever amazing speakers they already own. It even puts the album art on the full-color front display when streaming—a classy touch."

- Parker Hall and Michael Calore, WIRED Magazine, October 20, 2021

"If you value access to more music that you can possibly imagine (loved listening to Israeli Army radio late at night in Hebrew through the Internet Radio feature), phenomenal pacing, an engaging midrange that works with all genres of music, and want something that will take 5 minutes to set-up – the Uniti Atom is hard to beat. It’s not inexpensive but a brilliant piece of industrial design that positions Naim well for the future."

"A forward-thinking audio classic well worth the money."

- Ian White, ecoustics.com, October 11, 2021

"The Best Gear for Aspiring Audiophiles" - WIRED Magazine

"Streaming amps have gotten really great over the last few years. It used to be that anything with an internet connection sounded terrible, but that's not the case with the latest models. My high-end favorites right now are the Cambridge Audio Evo 150 ($3,000) and the Naim Uniti Atom ($3,290), which both feature gorgeous color displays and some of the best fidelity (and most glorious knobs) I've ever experienced. Both work with every major streaming service imaginable, and you can connect to them over Bluetooth too."

- Parker Hill, WIRED Magazine, June 5, 2021

"The Naim Uniti Atom is a near-perfect player. It has a wealth of connectivity and source options, an attractive design and a highly-usable app. Its screen is clear and colorful, and its playback precise and detailed. Pair it with a good pair of speakers and high-quality source material and it’ll bring new life to your favorite tunes."

"It’s undeniably expensive, but as a top-notch central home for all your music needs, it’s money well spent."

- Gerald Lynch, TechRadar.com, April 12, 2019

2021 Secrets Thumbs Up Awards

"Make no mistake, the Naim Uniti Atom is a $3300 component. At the same time, I’d be hard-pressed to find a pre-amp, amp, DAC, streaming system that sounds as good for less. If your tastes are high-end in equipment and music quality, adding a pair of speakers gets you a wonderful system for a study or a bedroom or a smaller living space."

"I’ll admit when I started that the Naim Uniti Atom seemed like a high-priced integrated amp with a nice, modern design. But after a couple of hours, it began to grow on me. The multiplicity of inputs, the elegant controls, the album art displayed on its front screen, and the dynamic and clean sound. Over time I began to appreciate the little things, like the well-designed app. So many Hi-fi companies have crappy apps that seem like afterthoughts. The iOS app is exceptionally thought out, and I expect the Android app is the same. All apps to control components should be this good."

"So, the Naim Uniti Atom has first-class build quality, reliable software (I saw no freezes or glitches during my testing), and it sounds as good as anything I’ve tested."

- Mel Martin, Secrets of Home Theater and High Fidelity, April 7, 2021

"Where the Uniti Atom truly scores is in the home of the music/audio enthusiast who wants a versatile, convenient, and elegant solution to streaming and playback of quality audio files with the highest fidelity using some of the best technology available today. It may even find a special place in the space that true audio nut shares with his or her family and/or significant other."

- John Richardson, Part-Time Audiophile, January 20, 2019

"Five Stars" – What Hi-fi? Magazine

"There probably aren’t two much more disparate pieces of music we could use for testing, but the Uniti Atom treats both with the same level of insight, regimental timing and contouring dynamics – and that's true of everything else we play that stylistically falls in between."

"In a way it would be easy to understate just how great a performer the Uniti Atom is, insofar as it’s kind-of what we have come to expect from Naim. But if you end up hearing one and fail to be excited at the prospect of ownership then, quite frankly, there’s little hope left for you."

- What Hi-fi? magazine, October 28, 2018

"Those who appreciate a satisfying a knob turn will find the Uniti Atom’s wheel a delight. As per my own experience with the Mu-so, the large rotary pulls me from my seat despite the remote and smartphone app being closer to hand. It’s simply more fun to wind the wheel than click psuedo- buttons."

"Naim seems to understand that pumping the volume is a sign that we want more. With the Uniti Atom’s wheel, the British manufacturer maximises the pleasure derived from the most enjoyable – and most fleeting – of musical moments. Add that to an amplifier whose audible qualities better lend themselves to modern music than starchy audiophile recordings and top it off with every streaming input under the sun and the Uniti Atom hits the DAR-KO Award bullseye: Future-Fi for the Music-First Audiophile."

- John H. Darko, Darko.Audio, July 2018

"Naim’s Uniti Atom is closely aligned with the way most people now listen to and experience music. With support for a wide range of protocols, including built-in AirPlay and Chromecast, there’s no limit to how you can connect your devices. The Atom also looks beautiful, with a generously large display that enhances the listening experience by providing a visual connection with your music. Last but not least, it sounds great, and can drive speakers ranging from bookshelf models to towers. It may have been a long time coming, but the Uniti Atom was worth the wait."
