Naim Audio Armageddon Power Supply
Housed in a single, HiCap style, extruded aluminium case, it contains a simple phase shift network. It does not use mains filters as we have found these to be sonically detrimental. (We came across one turntable supply that severely degraded the performance of several systems immediately it was plugged into the mains supply -- without even being switched on or connected to anything.)
The Armageddon drives the turntable at 33rpm (50Hz) only, with great smoothness and a dramatic reduction in the motor noise and vibration which cause irretrievable loss of information at the stylus.
