Overview

Our take on the Naim Uniti Atom

If you're serious about your music but want to keep your system simple, consider the Naim Uniti Atom. It's really three components in one. Its built-in amplifier, conservatively rated at 40 watts, will make all but the most power-hungry speakers sing. Its precision DAC circuitry will extract more musical clarity and presence from digital sources such as a disc player or TV. And with built-in Wi-Fi® and Bluetooth®, you can stream music from your phone or the web with the touch of a button.

High-quality parts, hand-wired analog and digital circuitry, and a massive power transformer (lower right) ensure outstanding sound.

Just add speakers

If you're serious about your music but want to keep your system simple, consider the Naim Uniti Atom. It's really three components in one. Its built-in amplifier, conservatively rated at 40 watts, will make all but the most power-hungry speakers sing. Its precision DAC circuitry will extract more musical clarity and presence from digital sources such as a disc player or TV. 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.

Naim Uniti Atom

Crutchfield customer from Minneapolis, MN on 11/19/2018

Crutchfield Customer Review (What's this?)

Amazing product. The future is here. Compact and very well built. Innovative design. The sound quality is excellent as well. Sounds more powerful than it's 40 watts suggest. It's not inexpensive but for the price there is not much else out there that can match it. The Naim application may not be the best but I've had no problems using it.

Pros: Build quality. Compact innovative design. Looks good. Sound quality.

Cons: Price is high but worth it. Wish Qobuz and Deezer were built into the Naim application like Tidal and Spotify is. Having to use Chromcast instead of the Naim application to control them is no fun.

Great sound ! Even Better Looks !

Sansbug from Kirkland, WA on 11/28/2017

Crutchfield Customer Review (What's this?)

I got this to upgrade my current digital music system. I must say that Naim has delivered both on sound and build quality true to the line of its fine audio products in such a compact package. The display is fantastic and so is the signature volume control on top of the unit. It is an eye-catcher, a conversation piece and a great sounding audio product for digital / streaming music lovers. I used it primarily as a streamer, DAC and preamplifier as i had it connected to a Mcintosh power amp driving my Martin Logans. Although you can use it as an integrated amp with bookshelf speakers. The highs, lows and midrange is all definitive. All you have to do is to hear "Hello" to fall for this piece. It could have been a five star keeper but the Naim app which is primarily what i was going to use for interacting with it was lacking at best. It needs to borrow a few pages from Sonos in the app department. Spotify connect & Tidal work flawlessly but then you really have to go to each individual app which makes queue management tricky. Chromecast wasnt that reliable. The Naim app only supports local music and Tidal integration tightly. I know Naim can do better than this in the app department. If they can fix the app by including universal search and queue management (Sonos style) they have a killer product.

Pros: Sound, Sound, Sound ! Volume Control. Conversation piece. The display and look is gorgeous.

Cons: Naim app lacks universal search across Spotify, Tidal, Local Music (NAS and USB). Q management needs work. Chromecast is buggy.
