The NDX, which will cost £2999.95 when it is available around October 2010, is primarily a UPnP renderer and Naim envisages most buyers using it to stream ripped CDs or high resolution downloads stored on a NAS, an HDX or UnitiServe. It will, of course, provide internet radio supported by vTuner’s services and it also features an on-board DAC with three inputs. Technically, these and the design of the NDX draw significantly on the acclaimed and widely successful Naim DAC. The innovative, SHARC DSP-based buffering with fixed clocks is used along with 16 times oversampling and Naim’s proprietary, low-generated noise, digital filtering algorithms. This enables non-Naim DAC owners to connect their computers, STBs, and other digital sources – their CD player’s digital output, maybe – through a Naim DAC, as opposed to the, superior, Naim DAC.

The unit can be upgraded with the Naim DAC and, naturally, with an XPS or 555PS power supply. In an all-too-brief demonstration we heard 1) the NDX, 2)NDX + 555PS, 3) NDX +555PS + DAC, and 4) the NDX +555PS with DAC +555PS. For me, combination 3 sounded the most satisfactory through 500-Series amplification and Ovator S600 loudspeakers. (The S-600s, incidentally, were sounding the best I have heard to date: far more musically persuasive that at their launch in Munich or at subsequent early demonstrations in the UK.)

The NDX can play all common, and some not so common, audio files and stream formats at up to 24-bit/96kHz resolution: WMA, MP3, MMS, AAC, Apple Lossless (from iPod), WAV, FLAC, AIFF and Ogg Vorbis. It also recognises M3U and PLS playlists formats and supports gapless playback on all lossless formats.

As the Wi-Fi antenna suggests, the NDX does wireless “for convenience,” says Naim. Which means use ethernet if you want the best sounding, most reliable performance.

你上面说的是NDX吗？

naim ndx 的价格，我还没有，还不了解这个东西和UNITISERVE的差别

ndx 和unaim serve，那个同轴输出的素质更高一些呢？国外的网站有没有介绍？

按照这个NDX可以升级的电源，似乎这个东西更加符合NAIM的规范啊，呵呵

要是国内可以有这个NDX供货的话，真就是没有必要进货UNITISERVE  SSD来实验了，没有中文，玩起来很点难，呵呵

老外说，同轴比光纤声音好。还特别崇拜naim dc1.

Naim NDX network audio player, £2995 inc five year warranty - now available from Rose Street Edinburgh

The Audiophile Network 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 gap-less 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 24 bit/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 iPhone app. 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.

Naim audio NDX network player

Naim NDX review
Can Naim's new high-performance streamer improve on the standard of its own CD players?

Read more: http://www.techradar.com/reviews/audio-visual/hi-fi-and-audio/audio-systems/naim-audio-ndx-940186/review#ixzz1JJP2rztG

The number of digital streaming devices available to the hi-fi enthusiast continues to grow on an almost daily basis. Each player seems to have a distinct musical character and its own particular selection of features. Take the new Naim NDX, for example.

This truly versatile machine provides network music replay, internet radio, digital iPod/iPhone connectivity and USB playback straight out of the box.

Its integral DAC is available to external sources – CD players, set-top boxes and the like – through three S/PDIF inputs. There is also an optional module for any buyer who wants to include FM/DAB radio.

DAC magic

The player follows Naim tradition in being performance-upgradeable through the addition of an XPS or 555PS power supply, along with the external Naim DAC.

You should probably regard adding the DAC as an icing-on-the-cake move, because the integral DAC in the NDX is based on the same technology and its performance does not lag too far behind. It uses the same innovative, SHARC DSP-based buffering with fixed clocks, along with Naim's proprietary 16 times oversampling and low generated noise, digital filtering algorithms.

The three S/PDIF inputs – two transformer-isolated coaxial and one buffered optical – will all accept signals at up to 24-bit/192kHz resolution.

Naim ndx

To stream music from computers and NAS (Network Attached Storage) units, the NDX uses the well-established UPnP (Universal Plug and Play) protocol. Naim has also written its own version of this for its sources, the HDX and UnitiServe, which can also act as UPnP servers.

We tested the NDX using these and the more widespread Asset and Twonky servers installed on two NAS drives. The NDX will operate wirelessly 'for convenience' but offers its finest and most reliable performances when connected by wire.

As Naim says: "Delivering music over a network is not difficult, but doing it well requires an attention to detail that is still surprisingly rare in today's market."

If you are prepared to pay for a player that boasts numerous features including extensive isolation to ensure the pristine transfer of data, along with Naim's legendary exacting retentiveness about the smallest of details, why should attaching it by a length of Cat5 or Cat6 cable pose any problems? Using wireless with an NDX seems on a par with fitting remould tyres to a Lamborghini.

The player will stream WAV, FLAC, AIFF, AAC, Windows Media formatted content, ALAC (from iPod), Ogg Vorbis and MP3 files from any appropriate UPnP server or USB-connected storage device.

The iPod connection is especially noteworthy: it is Apple-authenticated and it bypasses the DAC in the device and feeds a digital signal directly to the NDX and its rather more sophisticated and painstakingly optimised Burr-Brown PCM1791A DAC circuitry. This, for example, uses very similar RAM buffer and master-clock jitter-removal techniques as the 'big' Naim DAC.

The NDX, like other digital components in Naim's range features a Ground Selector switch that needs setting according to the rest of the components in your system to avoid earth loops that can, in the worst case, cause audible humming or, in less severe instances downgrade the sound. It has two options: to connect the earth to the chassis or to leave it 'floating'.

If you have a Naim CD player in your system, the floating selection is correct for all other Naim components where a choice is offered. If you are including the NDX in a predominantly non-Naim system, you'll need to take you dealer's advice or trust your ears.

Click on an image above and it will open a 300dpi suitable for print version

Product Overview

The NDX is a high-end network player designed to match Naim’s reference series products. For an existing Naim owner one might expect to see a NDX sitting in a Naim Fraim equipment support system alongside a CDX2 or CDS3 CD player. Naim envisage the owners of the NDX using it, primarily, as a high-end quality streamer playing back music ripped from CDs or hi-res music downloaded from the many online stores.

Technically, the NDX draws significantly from the hugely successful Naim DAC. The innovative and SHARC DSP-based buffering with fixed clocks is utilised along with 16 times oversampling and Naim’s proprietary, low-generated noise, digital filtering algorithms.

The NDX adds far more to a system than just streaming. It includes three S/PDIF digital inputs to support connection from computers to set top boxes to CD players.

It includes internet radio – the radio of the future –supported by vTuner’s five star full service. Search for stations by genre, location or just simply by name. New stations add automatically to the searchable database. Add special favourites or less common feeds to ‘added stations’ via the special Naim webpages.

Connect an iPhone or iPod digitally to allow the NDX to control and play all the stored music, podcasts or audiobooks. Play music on a USB stick, even hi-resolution WAV or FLAC files, with full onscreen control.

Control the NDX with the front-panel buttons, the supplied remote control or an iPhone or iPod Touch running the optional n-Stream app. The app also allows control of a Naim system’s inputs and volume.

Choose the optional FM/DAB module to add terrestrial radio stations. Maybe your favourite radio station has yet to start its internet radio stream.

Background

Just over two years ago, when Naim launched the innovative HDX hard disk player there was a shortage of streaming players and a real dearth of DACs. Now, there is no longer a shortage of either of these but there is still a significant shortage of players that deliver a true musical performance and not just shiny Hi-Fi sound.

Delivering music over Ethernet or Wi-Fi is not difficult, but to do it well requires an attention to detail that is still surprisingly rare in today’s market.

It requires control over every part of the chain possible. CD rips have to be undertaken correctly – a CD rip must be a secure rip. Storage needs to be fast, reliable (and of course backed up).The network needs to be well set up, with low collisions, and plenty of bandwidth.

Finally the player should be designed to be low jitter, reject the RF and other aberrations from noisy power supplies, mobile phones, the general environment and of course the EMI from computers. This is in addition to the standard audio requirements of technically measuring well, having a well-designed and hence good low-impedance power supply and good choice of components.

These are the basic building blocks. Then the attention to detail really counts.

Technical

The NDX has galvanic isolation between key sections of the circuits. This reduces the noise transfer to the analogue domain from the digital circuits and connections. Whether the NDX is playing from internal or external digital sources, the digital data is isolated from the DSP and in turn, the DSP is isolated from the master clock and DAC. There is maximum isolation between digital sources and analogue output. The power supplies for each section of the signal path are also independent. Four separate secondary windings feed four separate power supplies for isolation.

Naim’s buffer or memory method of jitter removal relies on a simple concept: the audio data clocks into the memory at the incoming inconsistently timed rate and then a precise clock controls the data out of the memory and into the DAC chips. Selecting the master clock that best matches the average incoming clock frequency, controls the rate at which the memory fills and empties. In this way, the data entering the DAC chips is completely isolated from the incoming jitter.

The NDX uses the same 16 times oversampling filter as the Naim DAC, implemented in the SHARC processor. The chosen filter is a modified Butterworth filter to which additional poles are added to prevent too much phase shift occurring within the audio band. The filter runs as efficiently as possible, using only five lines of assembly code. This ensures both low arithmetic noise (fewer additions and multiplications that cause rounding) and low power supply noise (since the DSP draws less current when it is not calculating).

The DAC in the NDX is a Burr Brown PCM1791A. It is used in 16 times external oversampling mode and runs at a maximum sample rate of 768 kHz.

The analogue output filter is multi-stage seven-pole filter. The design uses Burr Brown OPA42 opamps to perform the filtering; these are single chip opamps so a total of six are required. There is a plethora of audio opamps available but after many hours of listening tests, the OPA42 delivered the finest sound quality in this circuit. A combination of Sallen-Key and multiple feedback low pass filters are used to implement the seven-pole filter.

Reducing power supply (PSU) noise has long been part of Naim’s design philosophy. To increase perceived and measured dynamic range, PSU noise in the NDX is reduced to an extremely low level.

The NDX can be powered from its internal (integrated) PSU or as an upgrade an external Naim PSU; XPS or 555 PS.

The reservoir capacitors are larger than would typically be used to reduce the unregulated voltage noise and provide increased short-term current capability. The four separate PSUs form part of the electrical isolation of the Digital DSP section from the DAC chips and analogue circuits.

Low noise LM317/337 regulators smooth the unregulated voltage from the reservoir capacitors. Voltage supplies to many of the digital circuits are double and in some cases triple regulated to further reduce noise. Quadruple regulated if using an external supply.

When the PSU upgrade option is used with the NDX, power supply separation is maintained as the external power supply also has independent power supplies and ground connections. It also provides a significantly larger toroidal transformer and larger reservoir capacitors to further noise reduction.
