Recommend:

Ingress LV 3 roller ball & cup footers/30mm thick slate plate/a spring, in that order from top to bottom layer.

Full review coming soon.

Another point, @thyname. The Ingress should be set up with the ball directly touching the underside of the component and arranged in an equilateral triangle on plan.

@thyname, Ingress and Symposium roller and cup footers work well to damp seismic vibrations in rotational and horizontal planes. To get the best results you need to combine them with an air spring under a supportive plate made from a material with good damping properties.
