Naim · Classic 500 Series
The ND 555 is Naim's reference network player: a Burr-Brown R2R ladder DAC on a suspended brass sub-chassis, 40-bit SHARC processing and DR regulation, powered by the separate NAPS 555 DR.
Price is for the ND 555 only; it requires a NAPS 555 DR power supply.

The story
The ND 555 is where Naim's digital and analogue engineering meet at the top of the range. Its streaming board, the same generation as the New Classic, decodes PCM to 32-bit/384 kHz and DSD128 and oversamples to 40 bits in a SHARC processor before a Burr-Brown R2R ladder DAC. The DAC and analogue stages sit on a brass sub-chassis suspended to isolate them from microphony, LVDS signalling keeps timing noise down, and Naim's DR regulators condition every supply. Streaming covers Roon Ready, Qobuz, TIDAL, Spotify Connect, AirPlay 2, Chromecast and internet radio, with two optical, coaxial RCA and BNC digital inputs. Analogue output is on RCA and 5-pin DIN. The ND 555 has no internal power supply: a NAPS 555 DR is required, and a second one is the ultimate upgrade.
Naim designed the ND 555 to partner the NAC 552 and NAP 500 DR, and that is where it belongs: the reference digital source for a Classic 500 system. For a one-box streamer with a built-in supply and an upgrade path, the NSS 333 is the alternative.
Naim Classic 500 Series components are made in black anodised aluminium.
