Select products
Uniti Atom
- Positioning: The entry-level all-in-one streaming amplifier in the Naim lineup.
- Description: Features a compact design and high-quality sound, making it ideal for small rooms or as a secondary system. It features a 40W per channel amplifier and supports a wide range of streaming services, offering versatility similar to the Uniti Star but at a lower power output and without CD playback capabilities. This makes it a great choice for those with a moderate budget who prioritize streaming and connectivity over physical media.
Uniti Star
- Positioning: Sits in the middle of the Uniti range, offering more features than the Atom but less than the Nova.
- Description: Combines streaming capabilities with CD playback and ripping, which the Atom lacks. It delivers 70W per channel, providing a more powerful sound suitable for larger rooms or those seeking a more dynamic audio experience.

What if you spend more?
Product Strengths
- Sleek, understated, and elegant design with a substantial feel
- Comprehensive streaming support, including Apple AirPlay 2, Bluetooth (aptX Adaptive), Chromecast, Internet Radio, Qobuz, Spotify Connect, Tidal, and UPnP, and is Roon Ready
- Delivers music with a sense of immediacy
- Tight and detailed bass response
- The 5-inch LCD screen displays high-resolution album art
Product Considerations
- Is not a fan of heavily compressed or low-resolution content
- The Naim sound is not a lush sound and can err slightly on the 'harder' end of the spectrum rather than the warmer end
- The app has a laggy volume control
Comparisons (according to reviewers)
- Vs Uniti Nova: It offers more power (150W vs 70W), and it has tighter bass
- Vs NAD Masters M33: In terms of sound quality, they are likely on par, while the NAD may be a tad quieter and more transparent, the Naim is likely ballsier and weightier
- Vs Lyngdorf MXA-8400: Connecting the RCA preamp outputs of the Nova PE to the MXA-8400, to turn amplification duty over to the Lyngdorf, resulted in little difference in sound
- Vs JDS Labs Atom headphone amplifier: The Naim lacked some bass thump, most noticeable on Vanilla Ice's "Ice Ice Baby (Too Cold for Christmas Mix)"
Takeaway: The Uniti Nova PE is a well-built all-in-one system that combines modern styling cues with traditional aesthetics, and offers a powerful and engaging audio experience. It is a great choice for buyers seeking luxury and state-of-the-art sound in a convenient package.

Product Strengths
- Combines comprehensive functionality, connectivity and usability with good performance, and elegant design
- Exceptional sound quality is described as refined, muscular, detailed, confident, transparent, and natural

Product Considerations

- Naim's speaker connectors may be unique, although banana plugs are an acceptable workaround
- Although a detail performer, it isn't the quietest digital source or imaging performer in the market
Comparisons (according to reviewers)
- Vs Uniti Star: The Nova has a more substantial amplifier section, with greater current delivery and stability into tricky loads
- Vs SuperUniti: The Nova offers a more dynamic, detailed, fluid, and natural sound–with a bigger soundstage
- Vs Chord Electronics CPM2800 MkII: The Nova is closer spiritually to separates like the Chord CPM2800 MkII than to other all-in-one systems
- Vs NAD M10: The Naim Unit Nova has full unwavering control of the entire frequency range, from the deepest chest-thumping bass to the most delicate highs
- Vs Naim Uniti Atom: The Nova has more power to get a good result in bigger rooms, whereas the Atom needs to be in a smaller room
Takeaway: The Naim Uniti Nova is a well-designed and easy-to-use all-in-one system that combines comprehensive functionality with very good sound quality. It's a good choice for those who want a convenient and high-performing audio solution without the complexity of separates.

Our take on the brand
Enleum was launched as a new brand with the AMP-23R. While our legacy AMP-13R had already been praised all around the world for its performance and unique design, we pushed the boundaries to create the AMP-23R with a new circuit that truly enhances the existing performance. We have drastically improved the PCB circuit board design, chosen new internal components and upgraded our JET2 Bias design. And the reviews and awards are unanimous. The AMP-23R's physical size and footprint may be compact, but with the all new chassis and thermal heatsink design, we've launched a product that's fit for the next generation reference compact amplifier. The unique design is the DNA of our new Enleum Brand and was already awarded the Red Dot Award: Product Design 2021 and iF Design Gold Award 2022. The AMP-23R proudly showcases Enleum's expertise in technology and design.

Comparisons (according to reviewers)
- The AMP23R offers more texture, layering, mid-bass, and vocal presence than Nagra INT
- The AMP23R is more organic, ethereal, and dynamic than Kinki Studio EXM1
- It sounds better than the Vinnie Rossi L2iSE, so long as the speakers are easy to drive
- The Enleum has more delicacy and finesse than Pass Labs and Cary Audio
- The AMP23R stacks up with the finest gear such as ampsandsound Bryce monoblocks
- Pass Labs First Watt SIT-3 offers a bit more organic, warmer presentation
Takeaway: The Enleum AMP-23R is a small but mighty integrated amplifier with a unique and addictive sound signature, and it is built with high-quality components. It's a great choice for those with sensitive speakers looking for a reference-quality system in a compact package.

Video review
Our take on the brand
Our Summary
Product Strengths
- The M23's build quality feels solid and elegant, with impressive small design details
- The sound is striking in its purity and clarity
- It offers up to three levels of gain, switchable on the back panel, to best fit the system
- It provides a clear sound without sounding hard
- It features Purifi Eigentakt Class D amplification, which provides virtually unmeasurable distortion levels
Product Considerations
- The bass is clean but may be perceived as a little on the cool side and not as 'wompy-sounding'
- The M23 is not a forgiving amplifier that makes everything sound sweet and wonderful—it's not for those seeking a soft and mellow sound
- Bridging with speakers below 5 or 6 ohms is not recommended, as the amp will current limit and potentially shut down
- The reviewer found ergonomical challenges using fancy speaker cables in bridged mode due to wide terminal spacing
- The capacitive touch power button can accidentally trigger
Comparisons (according to reviewers)
- Vs Bel Canto C6i: The M23 offered a layer of refinement and better reproduction of the recording space
- Vs Pass XA25: The M23 had more transparent sound and detail, especially in the treble and upper mids, but lacked the organic quality of the XA25
- Vs HiFi Rose RS 520: The M23 sounded cleaner and had better separation/depth, HiFi Rose seemed to have an EQ built-in, emphasizing midrange and bass
- Vs NAD C298: The M23 is more neutral, deals with decay more naturally, and has better casework, making it look high-end
- Vs Anthem M1 monoblock amplifiers: The M23 was slightly more transparent throughout the entire frequency range
- Vs Bryston 4B 3: The Bryston had more grunt but the M23 is more neutral
Takeaway: The NAD M23 is a powerful and precise amplifier that delivers clean and clear sound, making it a great choice for audiophiles who want to hear their music as accurately as possible. It is especially well-suited for those looking to build a high-end system around a quality preamp or DAC.
