The Naim 555 PS benefits from the company’s decades of experience and 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 their 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.

A technical white paper on the Naim Audio Discrete Regulator technology is available here.

The Naim555PS was originally designed to partner the world-class CD555 CD player, the 555 PS can also be used with Naim’s ND 555, NDS, NDX and NDX 2 network players, their HDX hard disk player/ server and their DAC digital to analogue converter as well as the CDX2 CD player. Whatever Naim Audio product it partners, the Naim 555PS 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.

For Naim, 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 their portfolio.
