I figured it out. The squash balls simply pull out and then you have access to the screws that hold the cups that the balls sit in. Don’t know why I assumed it would be more complicated than that.
FYI I recently got some Stack Audio Auva footers for my speakers and thought they improved the sound so I got some of their Auva component footers and put them under the Amadeus. They work, now I have another set on order for my Sutherland phono stage.
