Ozzy, From talking to Jerry, I gathered that the PEAs will do particularly well when placed above the ventilation holes of a metal cabinet component. I used one to good effect on my Audio Magic Mini Ref, which has an acrylic cabinet. I expect that placing one on top of your PS audio would result in improvements to everything plugged into the regenerator.
With the other 2 units, I would move them around to see where they have the greatest impact. They can be velcroed to the speaker binding posts for instance.
