NAIM ND5 XS2 SLIM CHASSIS NETWORK PLAYER

The ND5 XS 2 uses Naim's innovative new streaming platform with an expanded feature set. High-res UPnP™ streaming, AirPlay, Chromecast built-in, Bluetooth (apt X HD), Spotify Connect, TIDAL, Roon compatibility, internet radio and multiroom streaming – alongside digital and USB inputs for conventional connections – make this versatile player the ideal partner for one of Naim's integrated amplifiers.

Carefully selected and matched parts, an oversized toroidal transformer, decoupled PCB boards: the ND5 XS 2 benefits from classic Naim engineering and fastidious attention to detail to ensure that it delivers natural, engaging sound quality from all sources.

Features

• Four 24bit/192kHz capable digital inputs (S/PDIF) to support optimum connection to external sources
• Built-in Chromecast allows you to stream from hundreds of supported smartphone or tablet apps (192kHz)
• Apple AirPlay - stream music from your iOS device or from iTunes and Apple Music
• Spotify Connect built-in to stream millions of songs from the world’s most popular streaming service
• Native support for TIDAL streaming service with free 90 day trial of lossless HiFi tier

Technology & Craft

The streaming section of the ND5 XS 2 uses the latest Naim network card featuring low-noise, 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, Naim's new streaming board turns things around and allows the 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 PCM1791A Burr-Brown digital-to-analogue converter.

Developing a new streaming platform was one of the biggest projects Naim has ever taken on. Naim engineers across all disciplines – electronic, industrial, acoustic and mechanical – worked for three years to create a system that could make the most of online services such as TIDAL and Spotify while adding future-proof flexibility through Chromecast built-in. Supporting faster data rates with dual-band Wi-Fi and the latest 802.11ac protocol, this robust platform was designed for the highest performance on every level.
