About Naim Uniti Atom Stereo Amplifier/Streamer

It's a cliche we know, but good things come in small packages. The Naim Uniti Atom is a combination amplifier and music streamer that just needs a pair of suitable speakers to deliver brilliant-sound. Now you've probably heard all that before, but we truly believe the Uniti Atom is uniquely versatile, seductively compact and, of course an irresistibly cute example of what contemporary music in the home is all about.

Uniti Atom is a beautiful, compact multi-source music player that will seduce you with its amazing sound quality and outstanding feature-set. Its 40-Watt integrated amplifier and high-resolution music streaming capabilities will fill your home with stunning high-fidelity sound. Atom is perfect as a high-end main system or even for use in the kitchen or study, where space is at a premium. Just add speakers. The Naim App for iOS and Android combines all of your music sources in one place, making Uniti Atom even more appealing.

Naim Uniti Atom

Conceived and built from the ground up by Naim's engineers and designers in Salisbury, England, Uniti remains true to their core design principles. The new signature illuminated volume dial, inspired by the reference Statement amplification system, is just one of the features in this beautifully engineered brushed aluminium chassis, which also boasts extruded heatsinks for thermal stability and a highly-polished full colour LCD glass display, providing you with rich imagery of your favourite album artwork. Impeccably crafted with materials chosen to be in complete service of sound, Uniti is alive with unique visual contrasts that make it a masterpiece of industrial design.

Naim have gone to extraordinary lengths to maximise the sound quality from such a compact all-in-one player. From the substantial transformer, which ensures that the power supply is always smooth and stable, to the sophisticated, hand-wired analogue and digital circuitry, every element of the design in Uniti Atom has been considered for its effect on sound quality.

Advanced Engineering

Revolutionary Streaming Platform: Everything about this new streaming board has been scrutinised to achieve the best possible sound quality. It’s much more powerful than its predecessor, has masses of memory, will adapt to new technology and seamlessly integrates across Naim’s existing product range, including the Mu-so wireless music system.

DSP and DAC: Uniti features an incredibly powerful 4th Generation 40-bit SHARC DSP processor. It’s so phenomenally accurate that it performs a staggering 2.7 billion 40-bit calculations per second, giving it enough power to resolve the most complex music signals with ease. The SHARC processor removes ‘jitter’ timing errors and using Naim’s RAM buffer (first used in the Naim DAC and NDS) oversamples the audio 16 times to feed the premium Burr Brown DACs, resulting in a smoother and more precise sonic performance.

A/B Amplification: Uniti uses Class A/B amplification, with technology derived from their iconic NAIT integrated amplifiers. Filter sections in Uniti Nova are made using the finest quality through hole film capacitors and discrete transistors with Uniti Atom and Uniti Star using a combination of through hole and Surface Mount Design (SMD). The power amplifier sections are now twice as fast, feature substantial transformers and run from linear power supplies.

Digitally Controlled Analogue Volume: At the heart of the Uniti all-in-one players is an audiophile volume control, adjusting level in the analogue domain to a premium digital resolution. The design is taken from the NAC-N 272 streaming preamplifier and its smooth structure is inspired by Naim's reference amplification system, Statement. Also the Bluetooth antenna has been hidden underneath the central dial for a seamless aesthetic.

State of the Art Wi-Fi: All Naim Uniti all-in-one players feature the very latest Wi-Fi. The superior Wi-Fi processor supports 2.4 and 5GHz, alongside much better internal buffer and memory. The Wi-Fi aerials (one on either side of the product for optimum range) are integrated behind a slot machined in the heatsink. Behind the aerials Naim have also installed a back reflector to prevent any harmful radiation from entering the unit, which further increases range, and of course, improves sound quality. This incredibly detailed patent-pending innovation provides robust connectivity without the need for an external aerial.

Storage: Play, store and serve up to 20,000 tracks from an external USB drive.

Command Your Music

Naim App: The intuitive Naim app gives you effortless control over individual or multiple Uniti products. You can access all of your music, including your favourite radio stations, streaming services and playlists, explore artist discographies and biographies, and you can now update your system wirelessly with a single tap.

Intelligent Remote Control: All aspects of Uniti’s design were considered holistically, including the design of a new bi-directional remote control...just in case you still wish to operate old style! Very early on Naim's R&D realised that passive IR remote technology was not going to deliver the targeted intimacy they wanted. A ground up solution, both from a technological and user point of view was sought and found with the bi-directional remote control. Beautiful white backlit buttons, a round volume display with segments that light up in harmony with the volume control on the player and easy pairing to any Uniti player, the remote is an intrinsic part of new Uniti.

Full Colour Display: With this range Naim wanted to deliver total connection to the user’s music collection. A highly-polished full colour 5” LCD display provides rich imagery of album artwork and content. The screens have proximity sensors and thus will wake up as someone approaches the machine to display music metadata, audio input information and more. There are also a selection of front panel buttons, including Favourites, Inputs and Play/Pause.

2019 What Hi-Fi? Awards: Uniti Atom - Best Hi-Fi System over £1,000

"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?
