Yes, Mike apparently will need help with all that wine.

Enjoy the music, not the equipment.

I just wanted to add myself to this weird phenomenon. My EP500 was thumping all by its lonesome self downstairs. Reciever was off, no signal at all going to the sub. A simple on/off reboot fixed the problem...

The ground loop was being caused by the Video Processor after all. It must have something to do with the AC/DC converter the VP uses. I used a ground isolation adapter on the VP and the thump went away. The humming I was getting with the addition of an amp went away too.
Rob, quite a few of us have done what you did. It’s the mystery thump. I know of at least two others besides myself, and now you, that have had to cycle the power to kill the thumping ghost. This last situation that I have been fighting is different.
