Full Description

DAB/FM Variant  +£335


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/iPod playback, thousands of internet radio stations, DAB/FM radio, digital inputs for external sources, multiroom streaming and a bespoke iOS and Android control app will get you listening to more music than ever before.  


Technology & Craft

Beneath NDX versatility lies one of the most technically ambitious and accomplished of all Naim 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'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 DAC outboard digital to analogue converter and all the oversampling, filtering and signal management techniques that have brought Naim 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 XPS or 555 PS power supplies to significantly enhance its performance. However, only Classic Series XPS units 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.



Streaming Versatility

Connected to an analogue or digital preamplifier input, NDX unlocks the potential of network audio. Its network connection can be either wireless or wired, and NDX can stream audio files, including iTunes libraries, stored on a computer or on network storage, via UPnP. It can play all common, and some not so common, audio file and stream formats at up to 24bit/192kHz resolution: WMA, MP3, MMS, AAC, Apple Lossless, WAV, FLAC, AIFF and Ogg Vorbis. NDX also recognises M3U and PLS playlists formats and supports gapless playback on all lossless formats.

NDX can play literally thousands of internet radio stations and an optional FM/DAB tuner module, that integrates seamlessly with the NDX control interface, is also available. NDX can play iPod or iPhone music via its front panel USB socket and, via the same socket, it can play audio files stored on USB memory sticks and drives. NDX is fully Apple Authenticated enabling playback of iPod/iPhone-stored digital media, bypassing the iPod/iPhone internal DAC for optimised performance.

Three independently selectable digital inputs enable S/PDIF audio signals from CD players, computers and other digital audio sources at up to 24bit/192kHz resolution to be handled by the NDX. Each digital input comprises a different connection socket option; optical TosLink, coaxial phono and coaxial BNC, to provide yet greater versatility and optimised sound quality.

Choice of control

Versatility and audio quality is worth nothing without an intuitive user interface and the NDX has three. It can be operated from its front panel buttons, from its remote control handset or using the Naim n-Stream app for iPad, iPhone and iPod Touch. The app also allows input and volume control of Naim preamplifiers and DAC.In each case, NDX control is simple, intuitive and satisfying.

Connected to a world of music

Connect an NDX to your existing audio system, and the world of network audio opens for discovery. It's a world of high resolution audio downloads, UPnP streaming, and the vast resource of internet radio. But thanks to Naim technology, it's a world of very high quality reproduction also, where music doesn't simply play in the background but lives, breathes and communicates.
