The 555 PS 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 transformer mounting, wire gauge, wire routing, mechanical decoupling, internal layout and reservoir capacitors. These improvements, developed through intensive listening tests, significantly raise performance and make music even more communicative and enjoyable.
The ultra-low noise 555 PS was originally designed to power the CD555 CD player but is also backwards- compatible with the CDS3 and CDX2 players. It can further be used to enhance the performance of the Naim HDX hard disk player and Naim DAC.
