Engineered to partner with Naim Statement or 500 Series amplification, the ND 555 incorporates Naim's NP800 streaming architecture with low-voltage differential signaling (LVDS), a 40-bit SHARC DSP engine, and dual Burr-Brown® R2R ladder DACs. The internal analog and digital stages are isolated on heavy brass sub-chassis suspended on tuned springs to minimize microphonic vibration.\u003c\/p\u003e\n\n\u003cp\u003eOperating exclusively with external Naim power supplies—such as the included flagship \u003cstrong\u003e555 PS DR\u003c\/strong\u003e—the ND 555 isolates sensitive audio circuitry from mains transformer radiation. The 555 PS DR utilizes Naim’s Discrete Regulator (DR) technology across seven regulated DC supply rails, powered by a massive toroidal transformer. Controlled via the Focal \u0026amp; Naim app, Zigbee remote, or front panel, the system supports high-resolution PCM up to 32-bit\/384 kHz, native DSD128, Roon Ready certification, AirPlay 2, Chromecast, and direct TIDAL, Qobuz, and Spotify streaming.\u003c\/p\u003e\n\n\u003ch3\u003eKEY FEATURES \u0026amp;
