Alternatives to Stillpoints

@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.

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.

Thanks for the advice @toetapaudio!

I have yet to receive the Ingress. Maybe next week. It's taking a while to get them from Canada

Even if you have a dedicated room for speakers and amps, equipment out of room is the best
