With its high-level performance, the versatile and upgradable NDX 2 represents the current state of the art. Loads of features such as UPnPTM hi-res streaming, Airplay, Chromecast, built-in Bluetooth (aptX HD), Spotify Connect, TIDAL, ROON compatibility, vTuner Internet Radio and multiroom along with digital and USB inputs provide you with all the connectivity of which you need.
However, our main focus during the development of NDX 2 remained on performance. Together with Naim's bespoke streaming platform, we have implemented and improved discrete analog DACs and stages. These and numerous other improvements over its acclaimed predecessors give NDX 2 incredible sound quality that translates into extremely lively and immersive music reproduction.

Technology and Construction
The Burr-Brown® PCM1792A digital-to-analog converter combined with our new streaming platform is one of the best available. We improved its performance by implementing a digital filter of our own design and adding a discrete current-to-voltage converter right after the DAC.
The streaming section of NDX 2 uses the latest low noise, high speed, low voltage differential signal (LVDS) network card. The higher speed allows decoding of all high definition audio formats up to 32bit/384kHz or DSD128. Instead of having the source manage the timing, the new network card works the other way around to allow the DAC clock to control the flow of audio data. The data is upsampled in a SHARC DSP to incredible 40-bit accuracy before being processed by the Burr-Brown DAC.
NDX 2 includes an ultra-low noise power supply with a specially designed toroidal transformer featuring separate windings for the digital and analog sections. In any case, the network player can be upgraded by connecting to XPS DR or 555 PS DR external power supplies to have a significant improvement in sonic performance and musicality.
During the development of NDX 2, our engineers looked at every detail, from mechanical construction to component selection and board layout. The result is a network player worthy of the Naim brand, with rich, detailed and immersive sound.
