NDX Network Player
The Performance Upgradeable, High-End,
Network Audio Player
The NDX is a network audio player with the potential to transform music in the home. It can play
UPnP™ audio streams, Internet radio, iPod or iPhone audio, and files stored on USB memory
hardware. Three high resolution S/PDIF digital inputs complete its versatility.
NDX is however more than just a versatile network audio player. It embodies Naim’s unrivalled
digital audio experience and knowhow to provide music reproduction quality equivalent to the
best-in-class CDX2 CD player and HDX hard disk player. It makes music with vitality and clarity,
rhythm and warmth. NDX defines a new class of high-end audio source equipment and brings
to it genuine audiophile performance.
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/96kHz resolution: WMA, MP3,
MMS, AAC, Apple Lossless (from iPod), 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 also fully Apple authenticated enabling playback of
iPod/iPhone-stored digital media, bypassing the iPod/iPhone’s internal digital to analogue converter
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 24 bit/192kHz resolution to be handled by the
NDX. Each digital input offers a different connection socket option; optical TosLink, coaxial phono
and coaxial BNC, to provide yet greater versatility and optimised sound quality.
Streaming technology
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, for example, the same RAM buffer and master-clock jitter
removal technique of Naim’s DAC outboard digital to analogue converter. It employs the same
Burr Brown digital to analogue converter chip as fitted to the HDX hard disk player, and all the
oversampling, filtering and signal management techniques that have brought Naim to the forefront
of digital music in the home. Component selection and layout on the six layer main PCB is entirely
optimised for sound quality and the classic Naim extruded non-magnetic aluminium case and
chassis construction ensures microphony is minimised. NDX is a true audiophile product where
maximising sound quality drives every development decision.
As with every Naim product, fastidious attention to power supply noise and regulation is a
fundamental element of NDX performance. A massive mains transformer, oversize smoothing
capacitors, independent power supplies and multiple regulators, along with painstakingly meticulous
PCB layout and earthing topology, ensure minimal power supply noise.
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 iPhone app. The app also allows input and volume control of most Naim preamplifiers and
DAC digital to analogue converter. 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.
For even better performance the NDX can be upgraded by the substitution of an outboard XPS or 555 PS power supply,
and, or the addition of the separate DAC digital to analogue converter.
