The 552 PS is the dedicated external power supply for the NAC 552 preamplifier. Power supply design has always been at the heart of Naim research and this project was no exception. For the NAC 552 a radical new split rail power supply configuration has been employed that almost eliminates power supply noise in the signal earth. Housed in a separate, full-width brushed aluminium case, the power supply features a massive 800VA toroidal transformer, three enormous smoothing capacitors and fourteen hand selected power regulators that independently supply the different stages of the preamplifier.
Naim Discrete Regulator
The 552 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 wire routing, mechanical decoupling and internal layout. These improvements, developed through intensive listening tests, significantly raise performance and make music even more communicative and enjoyable.
