Not everyone sees hi-fi as Naim Audio do. A smooth, stable, low-noise power supply isn’t just desirable: it’s fundamental to proper hi-fi performance. Nowhere is that belief more clearly exemplified than in the reference 555 PS DR, the best power supply in the Naim Audio portfolio.
Originally designed to partner the world-class CD555 CD player, the 555 PS can also be used with the ND 555, NDS, NDX and NDX 2 network players, the HDX hard disk player/ server and the DAC digital to analogue converter as well as the CDX2 CD player. Whatever Naim Audio product it partners, the 555 PS DR will improve every aspect of your favourite music. Voices and instruments become clearer and more natural. Perceived dynamic range increases too, while timing – music’s fundamental sense of rhythm and accuracy – snaps into even greater focus.

Technology & Craft
The 555 PS benefits from both decades of experience and Naim's relentless pursuit of superior sound quality. Its massive transformer, some 40 percent larger than that fitted to the XPS power supply, features five separate windings outputting to seven regulated supply voltages, including an output specifically intended for use with the clock circuitry of the CD555.
The 555 PS was updated in 2012 as a result of a two year project to develop a new discrete regulator (DR) for Naim Audio power supplies. The new Naim Audio DR now features, alongside improvements to the wire routing, mechanical decoupling and internal layout. These enhancements, developed through intensive listening tests, significantly raise performance and make music even more communicative and enjoyable.

Whether it is a CD-Player or an amplifier, whether components for €1000,– or €20.000,– each product features an unbelievable high musical value. Long term quality, which we get into over and over.
