Well, I haven't yet noticed any ill effects of appliances switching on/off, however there is no doubt that my late-2010 PP2000 model sounds different when running from AC vs. battery.

Also, when I switch from AC to battery, the output voltage (as measured by a true RMS voltmeter) INCREASES by between 3-4V. Now, I am NOT suggesting that this increase in voltage is causing the difference in SQ. However, it's 100% clear to me that the output of the PP2000 is different depending on whether it's being run from AC or battery.

I will say again that this is NOT what I paid >$3000 for... although I still continue to enjoy outstanding sound when the unit is running from its battery.

I will contact the retailer from whom I purchased my PP2000 to see what can be done about this.

Mani.
