flagship network player from Naim's legendary 500 Series, created for listeners who want the highest level of digital playback the company offers in its classic reference range.\u003c\/p\u003e\n\u003cp\u003eBuilt around Naim's most advanced streaming architecture, the ND 555 combines high-resolution network playback, sophisticated digital processing, extensive mechanical isolation, and a carefully engineered analog output stage in a reference-level source component designed to reveal everything contained in a recording.\u003c\/p\u003e\n\u003cp\u003eThe ND 555 does \u003cstrong\u003enot include an internal power supply\u003c\/strong\u003e and requires a compatible \u003cstrong\u003eNaim 555 PS DR\u003c\/strong\u003e for operation.\u003c\/p\u003e\n\u003cp\u003eThat external power-supply architecture is central to the design, allowing the sensitive digital and analog circuitry inside the player to remain physically separated from the large transformer and power-supply components.\u003c\/p\u003e\n\u003ch2\u003eA Reference Digital Source\u003c\/h2\u003e\n\u003cp\u003eThe ND 555 was developed to do far more than simply stream music.\u003c\/p\u003e\n\u003cp\u003eAt its heart is a powerful \u003cstrong\u003e40-bit SHARC digital signal processor\u003c\/strong\u003e, working alongside Naim's carefully implemented digital-to-analog conversion architecture and streaming platform.\u003c\/p\u003e\n\u003cp\u003eThe player was engineered around the same priorities Naim applies throughout its reference

output.\u003c\/p\u003e\n\u003cp\u003eThe ND 555 was engineered with that level of attention throughout.\u003c\/p\u003e\n\u003ch2\u003eSuspended Brass

digital source, but Naim approaches vibration control as seriously in its digital products as it does in its analog electronics.\u003c\/p\u003e\n\u003cp\u003eThe objective is
