Put painter's tape on floor to mark speaker positions.
Take pictures of knob positions on analog equipment (optimized settings)
Back up optimized digital settings (prepros, etc)
Lock the door
Get a cleaning robot (he usually a cutie...not a monstra like the cleaning lady or wife)
My cleaning woman doesn’t speak a word of English. I have given up on asking her not to move the speakers so I taped their optimal position on the floor and every two weeks spend 15 minutes readjusting.
