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.
About Naim Audio
Naim Audio is a British hi-fi manufacturer based in Wiltshire, United Kingdom. Naim began when Julian Vereker started Naim Audio Visual in 1969 and created a sound-to-light box that he hired out to film production companies. His disappointment with the sound of professional recording equipment at the time led him to design his own power amplifier. The company Naim Audio was incorporated in 1973. Against the conventional wisdom – dating back to audio pioneer Edgar Villchur – that the loudspeakers determined the sound of a hi-fi system, and that amplifiers were simply a means to an end in moving the speakers, Vereker set about to put his ideas into practice.
