Naim NDX network player

Compared to other established brands, Naim was a relatively late comer to the digital game.  But when they crossed over, they brought their analog amplifier experience with them.  Their first foray into digital music was in 1989 with the CDS-1 two-box player, considered one of the best in its time, and later its CD3 gained sort of a cult following.  


Zoom back to the 21st century, in addition to its  HDX hard disk player and Uniti all-in-one player, Naim has move on to the streaming player game with the NDX.  Think of it as a wireless DAC, the NDX plays UPnP audio streams, internet radio, iPod or iPhone audio, and files stored on USB memory hardware. Three high resolution S/PDIF digital inputs allow it to act as a stand alone DAC (up to 24 bit/192kHz resolution.)  Please note that it does not wirelessly play files on the iPod as it is not an Airplay compatible unit.

Its network connection can be either wireless (wifi) or wired (Ethernet LAN), and NDX can stream audio files, including from iTunes libraries, stored on a computer or on network storage, via UPnP. It can play all common audio file and stream formats at up to 24bit/96kHz resolution: WMA, MP3, MMS, AAC, Apple Lossless, WAV, FLAC, AIFF and Ogg Vorbis. The NDX also recognises M3U and PLS playlists formats and supports gap-less playback on all lossless formats.


NDX can also stream files from internet radio stations (optional FM/DAB tuner module available) and integrates seamlessly with the NDX control interface. 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.


All functions 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 other Naim preamplifiers and DAC. 

The NDX uses a RAM buffer and master-clock jitter removal technique of the top-of-the-line Naim DAC outboard digital to analogue converter. The digital to analog conversion function is handled by a single Burr Brown DAC chip.  NDX uses an extruded non-magnetic aluminium case and chassis construction with extra attention to power supply noise and regulation is a fundamental element of its performance. A massive mains transformer, oversize smoothing capacitors, independent power supplies and multiple regulators, along with meticulous PCB layout and earthing topology, ensure minimal power supply noise.
