NAIM NDX2

Pre owned. In good conditions. The only visible sign of wear concerns one of the two Wi-Fi antennas, as shown in the photo. Supplied with remote control, original packaging, and manual.

The Naim NDX 2 is a network player that represents the pinnacle of modern audio engineering. From the very first listen, it stands out for its engaging and dynamic sound reproduction, capable of enhancing every nuance thanks to a proprietary streaming platform and a Burr-Brown PCM1792A DAC paired with an in-house designed digital filter. Careful signal management, including discrete current-to-voltage conversion, ensures a natural, precise, and satisfying sound performance.

The completely redesigned network section uses a low-noise board with LVDS differential signaling, ensuring high transfer speed and flawless decoding of high-resolution files up to 32-bit/384kHz or DSD128. The internal clock manages the data flow, which is oversampled by a powerful 40-bit SHARC DSP before reaching the DAC. Every element is designed to preserve signal integrity and minimize jitter.

The NDX 2 offers comprehensive connectivity: compatible with UPnP, AirPlay, Chromecast, aptX HD Bluetooth, Spotify Connect, TIDAL, Roon, Internet Radio, and multiroom functionality, all controlled intuitively through the Naim app for iOS and Android. It supports a wide range of audio formats, including WAV, FLAC, DSD, Apple Lossless, AIFF, and MP3, and ensures seamless gapless playback. It features four digital S/PDIF inputs, front and rear USB ports, RCA and DIN analog outputs, and a coaxial digital output for high-end external DACs.

The clear and bright 5-inch color display offers a modern interface showing album artwork and track information, enhancing the user experience. Build quality is evident in every detail—from the solid chassis to the layout of internal components. Special attention has been given to the power supply: the custom-designed toroidal transformer has separate windings for the digital and analog sections, reducing noise and improving circuit separation. For those seeking the ultimate performance, the NDX 2 can be paired with Naim's external power supplies such as the XPS DR or 555 PS DR, providing a significant sonic upgrade.

In use, the NDX 2 offers exceptional responsiveness and rare smoothness, even among high-end streamers. It transitions effortlessly between high-res streams without delay or interruption. Whether playing refined electronic music or complex rhythmic passages, the sound remains controlled, precise, and richly textured. Its ability to render detail and musical structure makes it one of the most compelling choices in its class. Even without optional external power supplies, the NDX 2 proves to be an outstanding network player—built with care, designed to last, and backed by a brand with a long-standing tradition.
