I live where we loose power about once a year due to downed trees during a storm. When I see the wind is going to be significant I throw the stereo 20 amp breaker in the main panel. If in fact the power does go out
then I throw a whole lot of breakers to prevent the surge from hammering appliances. I use a PS Audio Stellar Powerplant 3 which is good for a continuous 300 watts. Only source components are powered by it. Amps are plugged directly into the wall. The source components draw just under 100 watts. And somewhat surprisingly to me that doesn't vary with volume, I did think that the tube pre would vary a bit with volume.
