Linear Power Supply Option (All versions of Sutherland 20/20)
For many years now, switching power supplies have been used at many price points by many manufacturers of high-performance audio. For adequate performance, special attention must be focused on two aspects of mitigating the noise they inherently generate. High frequency switching devices leave a high frequency ripple component in the DC output voltage. It must be effectively removed. Also of concern is keeping current spikes on the primary side from injecting noise into the AC power line. If that is not dealt with, the switching power supply will pollute the quality of AC power available to all the audio system components.
Sutherland has been using switching power supplies on several models and now offers an upgrade Linear Power Supply specifically for the popular 20/20 design.
