NDX 2

Streamlined connectivity from an exceptionally engaging network player

With its world-class performance, the versatile and upgradable NDX 2 embodies the current state of the art. A host of features such as high-res UPnPTM streaming, AirPlay, Chromecast built-in, Bluetooth (aptX HD), Spotify Connect, TIDAL, Roon compatibility, vTuner internet radio and multiroom streaming as well as digital and USB inputs provide all the connectivity you could wish for.

Our main focus in developing the NDX 2 network player, however, was its performance. Along with Naim’s bespoke streaming platform, we implemented an upgraded DAC and discrete analogue stages. These and numerous other improvements over its acclaimed predecessor make the NDX 2 a sonic force to be reckoned with, offering highly immersive and lively replay quality.

Technology & Craft

The Burr-Brown® PCM1792A digital-to-analogue converter working alongside our new streaming platform is one of the best available. We improved its performance even further by implementing our own digital filters and adding a discrete current-tovoltage converter immediately after the DAC.

The streaming section of the NDX 2 uses the latest Naim network card featuring lownoise, high-speed low-voltage differential signalling (LVDS) to route the digital audio signal. The higher speed is capable of decoding all HD audio formats at up to 32 bits/384 kHz or DSD128. Rather than the source acting as the digital timing master, our new streaming board turns things around and allows our DAC clock to control the flow of audio data. The data is integer-over-sampled in a SHARC DSP to an incredible 40-bit accuracy before it’s fed to the Burr-Brown DAC.

The NDX 2 features an integrated low-noise power supply with a custom-designed toroidal transformer and separate windings for the digital and analogue sections. However, the player can be upgraded with an external XPS DR or 555 PS DR power supply, giving you a marked increase in sonic authority and emotion.

During the development of the NDX 2, our engineers examined every detail, from mechanical construction, component selection and board layout. The result is a network player worthy of the Naim badge, with a sound that’s rich, detailed and engaging.

Latest Reviews
HI-FI World | NDX 2 | 5 Globes , Sep 2019
"Sonically it was supremely well-honed, something of a reference for what is possible from streaming."
HI-FI+ | NDX 2/XPS DR | Review , May 2019
“The Naim reflects the intrinsic nature of both the recording and the music with everything you choose to play.”
What Hi-Fi? | NDX 2 | 5 Star Review, Feb 2019
'For most, a stand-alone Naim NDX 2 will be all the streamer they could ever want. It is well made, carefully conceived and sounds excellent for the money. Naim also has a great track record on supporting its products, which really matters when the investment is as heavy as this. In short, buy the NDX 2 with confidence.'
The Ear | NDX 2 | 5 Star Review, Feb 2019
'This is a fabulous streamer, use it with a very good server and you are guaranteed digital musical entertainment that will keep you enthralled for years. It shows you precisely what’s going on and brings out what’s special about the music, and that’s what you want from a piece of audio electronics.'
Fairaudio | NDX 2 | Hi-Fi Test , Nov 2018
Rather sonorous and razor-sharp pulse playback and analytical access to the air belt … is rather rare, right? No, just as the Naim does that, it seems coherent: music should come across tangibly, authentically and physically.
NDX 2 | Hi-Fi Critic, Sep 2018
Clarity, image depth precision and dynamics are a prime strength, while still greater resolution and improved timing may be had with those optional extra power supplies. An Audio Excellence rating seems appropriate for the NDX 2/555 PS DR combination.
Network Players Press Event | Hi-Fi+, Apr 2018
'First Listen – Naim ND5 XS 2, NDX 2, ND 555 streamers'
Network Players Press Event | What Hi-Fi, Apr 2018
