About the ND 555
The Naim ND 555 is a state-of-the-art network player that combines decades of digital and analogue engineering expertise. It features a powerful 40-bit SHARC DSP processor that performs advanced jitter removal and integer oversampling to 40-bit accuracy. The digital audio signal is routed via low-noise, high-speed LVDS to minimize timing errors and interference. The ND 555 uses the Burr-Brown PCM1704, a true R2R ladder DAC renowned for its musicality and analog-like sound. The player supports high-resolution audio formats up to 32-bit/384kHz PCM and DSD128, converting DSD to PCM internally. It includes Naim's DR regulator technology with 13 discrete regulators to provide ultra-pure DC power to sensitive audio circuits. The analogue stages are built with high-grade through-hole components and mounted on a suspended brass sub-chassis to reduce microphony and vibration. Control is available via the Focal & Naim app, a premium Zigbee remote, or the front panel's 5" color display. Connectivity includes USB (front and rear), optical and coaxial digital inputs, and network interfaces supporting Wi-Fi and Ethernet. The ND 555 is designed to be paired with Naim's 555 PS DR external power supply and high-end amplification for a live music-like experience.
