Description

NDX. Streaming technology for music. 

The world’s first audiophile network music player, the NDX remains an exceptional streaming solution, surpassed only by the NDS. Its performance-oriented design retains the single-component convenience of the ND5 XS, but includes a significantly improved power supply with a custom-designed toroidal transformer plus four separate windings for its digital, DSP, clock and analogue output stages.

The performance of the NDX is matched only by its digital versatility. High-resolution UPnP network streaming, Spotify Connect, USB playback, thousands of internet radio stations, DAB/FM radio, digital inputs for external sources, support for TIDAL lossless audio service, multiroom streaming and a bespoke iOS and Android control app will get you listening to more music than ever before.

  • iOS and Android Naim Audio app for intuitive control
  • Bluetooth connectivity with aptX codec for quality audio playback
Technology & Craft

Beneath NDX versatility lies one of the most technically ambitious and accomplished of all Naim Audio products. The wide variety of digital audio data streams and signal types, and the necessity that each one is delivered to the NDX outputs with maximum fidelity, demanded first that many new and innovative techniques for electronic signal isolation had to be developed and refined. The full spectrum of Naim Audio's uniquely advanced digital signal handling and processing techniques is also deployed in the NDX.

The NDX uses the same RAM buffer and master-clock jitter removal technique of the Naim Audio DAC outboard digital to analogue converter and all the oversampling, filtering and signal management techniques that have brought Naim Audio to the forefront of digital music in the home. NDX is a true audiophile product where maximising sound quality drives every development decision.

The NDX can be used in conjunction with the XPSor 555 PS power supplies to significantly enhance its performance. However, only Classic Series XPSunits are compatible with the NDX, not the older Olive Series versions.*

* Please note: only current "Classic" style XPS power supplies can be used with the NDX. Older "Olive" style XPS units are incompatible and cannot be used.

 
Designer

Why Naim?

Every Naim product is conceived, designed and engineered entirely in service of the sound, revealing a pure experience of music that is as close as possible to its original live source.

We believe that the exploration of sound is an adventure that rewards you with a clarity and connection that becomes more powerful the deeper you travel within it.  Which is why, every element within our systems is crafted to create a silence around the sound, reducing any interference between you and the intention of the artist.  We achieve this through tireless attention to four fundamentals in our engineering:

1. Space

We give each of the critical components their own environment, omitting outside or ‘toxic’ interference, which means no compromise on the purity of sound.

 

2. Circuitry

We minimise any interplay between the internal levels, so that you can simultaneously enjoy both the quiet and the loud, as originally intended.

 

3. Purposeful materiality

We use materials that excel in performance, not just appearance.

 

4. Technology

We constantly strive for new and innovative ways to achieve our goals, integrating sophisticated electronic design and software development, with mechanical engineering and acoustics to deliver a truly advanced sonic experience.

By managing the relationship between these four pillars of engineering we enable our listeners to hear every single note in equal measure and transcend from audio sound to musical performance. We call this unique and emotive transmission the ‘Voice of Naim’; it’s our signature, our calling card.

This ‘voice’ has been carefully engineered across our product portfolio and crafted to take you the listener deeper through this journey into music, from the excellent entry-level Mu-so wireless range, through to the ultimate listening investment in our ‘Marque’ separates - Classic, 500 and Statement, our flagship amplification system.  

Let the voice of Naim take you inside the music… Go Deeper.

The Naim Audio Way

Ever since the early days we’ve ignored trends and trusted our own sense of what matters most in music playback. 

How we Listen 

No matter how vanishingly low we’ve managed to make distortion and jitter or how well we’ve controlled power supply noise and interference, we will always make our final judgement on a product in the listening room. Every component has to earn its place.

When we listen it’s not just for technical competencies. It’s about being able to forget that you’re listening to hi-fi at all and becoming immersed in a complete experience, feeling all the emotion that the artist intended when they first created the music. 

Built to last

Built to last

Unlike most other consumer electronics, Naim Audio products are not designed to be replaced in three to four years. Buying a Naim Audio product is an investment in many years of incredible musical experiences. It’s a choice to make music a central part of your life.

We can still repair almost every product we’ve ever made in our service and restoration department. The skilled technicians there are some of our most experienced, with the know-how to breathe life into classic Naim Audio equipment. They regularly restore some of the first hi-fi products we ever made, ready to provide another 30 years of musical enjoyment to their owners. 

If your product is over 10 years old then it’s a good idea to send it back to us for some care and attention. You can book in a service with our Customer Support team.

 

Performance upgradable

Performance upgradable 

Once you’ve chosen Naim Audio you may find that you crave for even more of the musical performance that our products deliver. The good news is that there is usually an upgrade path which will allow you to attain the next level of performance without having to purchase a completely new system. That could be as simple as upgrading to a Power-Line mains cable, opting for an additional power supply or even making the move to separate pre and power amplifiers.

Infinite Curiosity 

It takes infinite curiosity to be a Naim Audio engineer. To define, test and redefine each component and material in every product we design, ignoring trends to find new and better ways to achieve state of the art performance.

The SNAIC Shaker

Every Naim Audio interconnect is shaken 180 times by a custom-designed pneumatic production device affectionately named ‘The SNAIC Shaker’ by our technicians. Why do we do this? Because it improves sound quality.

40-point Floating Point Digital Filter
40-point Floating Point Digital Filter

The digital filter in the NDS is mathematically precise enough to count 2 32 x 2256 seconds (that’s a 5 followed by 86 zeros). In other words, it’s powerful enough to count every second since the universe began many times over with pin-point accuracy. This level of precision is essential in order to keep filter arithmetic noise below – 144dB (the theoretical signal-to-noise ratio of 24bit PCM audio) at all times for best sound quality.

Absolute power
Absolute Power

Nowhere is our determination to dance to the beat of our own drum more apparent than in our understanding of and enthusiasm for better quality power supplies. Improving the power supply has a clear and tangible effect on sound quality, we’ve observed it over and over. It’s why Naim products carry large transformers with isolated windings. The philosophy is exemplified in our range of separate power supplies that have the sole purpose of providing smooth, stable and low-noise power for audio electronics to shine. 

Decoupling and isolation
Decoupling and Isolation

Minimising mechanical, electromagnetic and thermal interference between components is a key part of Naim Audio design. Decoupling sockets to cut off interference from incoming mains power and suspending circuit boards on brass sub plates to create an isolated environment for critical electronics are two applications of this principle. A less obvious example is the creation of small bends in individual resistors by hand, decreasing microphonic interference (microscopic vibrations which degrade sound quality). But similar techniques are applied at every level of the design and build. And we only introduce techniques if they prove effective and repeatable in listening tests.

Hand-Matched Components
Hand-matched Componentry

Matching the characteristics of sound critical components for each channel (left and right speaker) of an amplifier can greatly improve sound quality. Batches of resistors typically come matched to within a 5% margin of error. Through listening tests we found that if the resistance of the left and right channels are matched to closer than 0.5% music becomes dramatically more communicative and engaging. Following this discovery a bespoke production procedure was conceived to help us match resistors by hand.

Julian Vereker - Naim Founder

Our Story

Our story begins with one man’s passion for music and weaves its way through four decades and a raft of iconic product launches to the present day.   

Naim Audio founder Julian Vereker MBE (1945-2000) was a racing car driver, entrepreneur and self-taught engineer with a deep passion for music. Spending his spare time listening to and recording his friends playing live in the 1960s, Julian found that playback on his system at home fell woefully short of the experience he craved.

Not content with second best he decided to design his own amplifiers and loudspeakers, ignoring accepted wisdom and focusing on aspects of performance that made music burst to life. These first designs laid the foundations for a range of iconic and award-winning hi-fi products that would reach well into the next century.  

1969 Humble Beginnings
1969 Humble Beginnings 

Frustrated with the quality of music reproduction after recording his friends playing live, Naim Audio’s founder, Julian Vereker turned from building his own racing cars to experimenting with amplifiers.

1972 A first start at Capital Radio
1972 A first start at Capital Radio 

Julian won a contract to supply then start-up radio station, Capital Radio, with audio equipment. The successful design was a compact version of an early Naim Audio power amplifier combined with speaker drive units in one cabinet – the NAM 502.

1973 Naim Audio Officially Founded
1973 Naim Audio Officially Founded

Following the success of Capital Radio, Naim Audio was officially incorporated in 1973 with Julian Vereker and his co-founder Shirley Clarke as directors. Based in a shop in the centre of Salisbury, our first HQ had both manufacturing and demonstration facilities. 

1973 The NAP 200 Power Amplifier
1973 The NAP 200 Power Amplifier

Our first consumer product for home use was launched in the year of our founding: the NAP 200 power amplifier. Originally designed in 1971, its descendant power amplifiers differ greatly technologically but still aim for the same performance goals of pace, rhythm and timing. 

1974 The NAC 12 Preamplifier
1974 The NAC 12 Preamplifier

With a network of dedicated independent retailers now on board in the UK, the NAC 12, our first production preamplifier, was launched. 

1980 Classic Advertising

As Naim Audio grew in popularity through the 70s and early 80s, the team decided to grab the attention of the press and public with a series of tongue-in-cheek adverts. They reflected the confident, often unorthodox nature of our approach to music playback and have become iconic in their own right. 

1983 NAIT Integrated Amplifier
1983 NAIT Integrated Amplifier 

Naim Audio’s first integrated amplifier the NAIT introduced. This iconic little integrated amp sounded quite unlike any other integrated of its day and set a trend for so-called ‘super integrateds’.

1985 Brompton Connection
1985 Brompton Connection 

Julian joins friend and fellow inventor Andrew Ritchie at his newly founded company. Their product is an innovative bicycle which can be quickly and easily folded up for transportation and storage. He backs the business and becomes a director, helping them to set up production and eventually to become one of the most iconic British brands in the world: Brompton Bicycle.

1985-queens-award
1985 The Queen's Award

Naim Audio is recognised with the prestigious Queen’s Award for the first time in 1985. We would go on to repeat this achievement a further two times in the 21st century, winning for Export in 2010 and for Innovation in digital music streaming in 2014.  

1991 The CDS CD Player
1991 The CDS CD Player 

Like so many Naim Audio products, the design of our first CD player, the CDS, flew in the face of conventional wisdom. Its two box configuration gave the power supply its own separate enclosure and the CD clamp used a rare earth magnet to keep its mass low whilst still firmly holding the disc without vibration.

1993 Naim Records is Born

Created by Naim founder Julian Vereker, Naim Records combined his love for music with his quest to deliver the best sound quality, from the studio to the listening room.

2000 NAP 500 Power Amplifier
2000 NAP 500 Power Amplifier 

The year 2000 marked a step change in Naim Audio history. After several years in development, the new flagship Naim Audio NAP 500 power amplifier was born and with it the new industrial design aesthetic that would redefine Naim Audio for the 21st century. Its music-making ability would only be bettered by the arrival of Statement in 2014. 

Naim for Bentley
2008 Naim for Bentley 

Two brands with a distinguished British heritage and a passion for engineering excellence share an 18 month development project to produce the Naim for Bentley in car system. Using sophisticated Naim Audio DSP (Digital Signal Processing) and speaker drive unit technology, the system is available as a custom extra on all Bentley models. 

2009 NaimUniti
