Hi, Good info. This all was brought home to me about 3 weeks ago. My system is on an APC HL-10 power conditioner. One feature is that it will boost or cut the voltage to keep it at the level set. Also within the % you choose. I have it set for 120 with 5% as the limits. It started boosting one day just before Christmas. It was transparent to the stereo as it apparently has zero crossing switching, but the display indicated the boost. It turns out that the one outlet in another room that had my wife's laser printer on it was dropping the line enough to cause the triggering. In my former stereo room (now taken over by the wife as a media room ) I had dedicated power and this never happened.
