Naim 555PS DR Power supply with Powerline
Voltage regulators are widely deployed within Naim power supplies to ensure that audio and digital circuits operate with a stable, low noise supply voltage, thereby maximising their performance. The new DR equipped power supplies from Naim feature their new discrete regulator which betters industry standard monolithic voltage regulators. The whole of the power supply has been reviewed and updated, they now feature reviewed transformer mountings, wire gauge, wire routing, mechanical decoupling, internal layout and reservoir capacitors.
Within the supply's low resonance case with isolating feet there is a transformer that is 40 percent larger than that in the XPS with five secondary windings outputting seven regulated power supplies including a separate one for the CD555 clock circuitry. The 555 PS also has separate dedicated analogue and digital output sockets (Burndy) to minimise high frequency noise modulation of the analogue supplies. 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 is also an essential part of the ND555 network streamer and can further be used to enhance the performance of the Naim HDX hard disk player and Naim DAC.
