External Audio Power Supply

This external power supply is manufactured for use with 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.
