The ND 555 is the first product launched in the 500 Series by Naim Audio in more than a decade and effectively replaces both the now discontinued CD 555 and NDS, as the source of choice.
The ND 555 has no internal power, requiring either one or two separate 555 PS DR power supplies. Like the rest of the 500 Series, it places great importance on PCB isolation and vibration control, with the circuit boards for conversion and amplification resting on high mass brass spring board platforms, to de-couple the PCBs from any vibration above 10Hz. Thirteen of Naim’s own DR voltage regulators feed the power supply! Add to this two laser-trimmed, selected PCM1704U-K resistor ladder DAC chips and a fourth generation SHARC chip for DSP, filtration, and buffer wrangling. A Naim Power Line mains lead and a Hi Line Din to Din is also included.
Designed to perform to higher sampling rates than its predecessor; up to 32-bit, 384kHz PCM, and DSD 128. The ND555 is Roon ready, supports gapless playback, Tidal, Spotify Connect, Apple AirPlay and Google Chromecast. The ND 555 features a five-inch TFT colour display and four hard-buttons.
So how does it sound?
In a word: Astonishing!
We have played numerous tracks, CD rips and 24 bit downloads from the Naim Core as well as Tidal CD quality streams. The Naim ND555 sounds so much better than ANY other streamer that we have ever heard. Scale, detail, dynamics, resolution, cohesion, it’s as near to perfect as you can imagine. Some streamers can struggle to convey the emotional content in music, not so the ND 555.
OK, so it will cost you £20,000 to own one, but for the performance it offers, it could just be considered a bargain!
Come and have a listen and be prepared to be smitten!
