Naim 555PS DR Black High End Power Supply

Full Description

The ultimate upgrade, for a smooth, stable, low-noise power supply. This isn't just desirable: its fundamental to proper hi-fi performance. Nowhere is that belief more clearly exemplified than in Naim's reference 555 PS DR, the best power supply in their portfolio.

Originally designed to partner their world-class CD555 CD player, the 555 PS can also be used with Naims NDX network player, and their DAC's 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. 

The 555 PS benefits from both Naims decades of experience and their relentless pursuit of superior sound quality. Its massive transformer, some 40 percent larger than that fitted to their XPS power supply, features five separate windings outputting to seven regulated supply voltages.

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.
