555 PS DR Power Supply

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 555 PS, the reference Naim power supply.

Description

Originally designed to partner our world-class CD555 CD player, the 555 PS DR can also be used with the NDS and NDX network players, the HDX hard disk player/ server and the DAC digital to analogue converter as well as the CDX2 CD player. Whatever Naim product it partners, the 555 PS 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.

The 555 PS DR benefits from both Naim’s decades of experience and their relentless pursuit of superior sound quality. Its massive transformer, some 40 percent larger than that fitted to our 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 our CD555.

The 555 PS DR was updated in 2012 as a result of a two year project to develop a new discrete regulator (DR) for Naim power supplies. The new Naim 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.
