Well, with my unit, you are right under one condition. It does not matter if I am on the battery or the ac line as long as the unit is connected, it sounds the same but it does not perform good. However if I am on the battery and I disconnect the regen from the ac, either by physically taking the plug off the wall, or switching the interrupter switch off, then there is a great lowering off the noise floor. The unit performs great from just the battery disconnected from the wall.

This has been an on-going controversy. I too hear differences at different times of day and sometimes randomly. In my case the differences are reduced from just using wall AC. But the PP was only somewhat better for me than using PS Audio Ultimate Outlets (baluns) on each component. The isolation does not seem complete but the extent of the non isolation may be due to QC issues with the unit or the wall AC at the site or interactions with other components etc. You do seem to be suffering from a more extreme condition of isolation breach than I am. But I am hearing it as well so it is a question of degree. All you can do is try different outlets  or try it in different rooms if you can. Also you might check your residence wiring. Best of luck.
