Naim 555 Reference DR Power Supply

Long seen as critical to high end audio a quality power supply lifts all applicable components to a new level of enjoyment. First seen on the release of the remarkable CD555 the 555 PS DR has gone on to bring its magic to a number of Naim Audio products, namely 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.

Features
    Seven regulated supply voltages, including a separate supply for the CD555 clock circuit
    Low-resonance case with isolating feet
    Massive transformer, 40 percent larger than that fitted to the XPS
    Supplied with Power-Line mains cable as standard
    All-new Discrete Regulator (DR) configuration, delivering Naim Audio’s best-ever standards of stable, low-noise power

Technology & Craft

The 555 PS benefits from both our decades of experience and our 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 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.

Update concerning Powerline / Power Cables.
Effective immediately, all Naim 500 series components will be shipped
with standard AU/NZ power cables.These units had previously been supplied with Powerline, cut and
terminated in Australia with Australian plugs. Naim engineers report the cable too thick
to comfortably fit, therefore compromising the principle of the Powerline cables.
