@audiom3 Im very interested in the springs you mentioned. Can you provide the link so I can find them? Thanks!
I would say, though, that the most universally-praised tweak I’ve ever heard of are the Townshend Seismic isolation products that are based on springs, hence my interest in the cheaper springs above as the Seismic products are not cheap. But, without exception, the reviews and customer feedback I’ve read on all Seismic products have been exuberantly positive in every application (speakers, components, equipment stands, etc.) — something I’ve very rarely found with tweaks.
