Naim Audio ND555

Categories: , , ,


  • High End Streamer
  • Now also with Native support for Qobuz!
  • Upgradable with a second external 555 PS DR power supply.


Naim’s reference network player is quite simply the best source component Naim has ever. Drawing on decades of digital and analogue engineering experience, the ND 555 marries Naim’s innovative new streaming platform with classic analogue technology. It features a 40-bit SHARC processor with advanced signal processing, a suspended brass sub-chassis to isolate sound-critical circuits from vibrations and the best external power supply we’ve ever made. Whether you’re listening to Bonham’s solid groove or Coltrane’s dizzying scales, the ND 555 lets the music flow with astonishing ease and uniquely engaging musicality. Partnered with Statement or 500 series amplification, we believe the ND 555 is as close to live music as it gets.
