There was a company called Reference Stands that made VERY high quality stands during the early 90's. I have seen them at AudioPrism's Byron Coletts' home and FIM Cables Winston Mas' home. Maybe there are some out there on the used market? There were many models, all built over kill, with heavy wall aircraft aluminum pipe and large isolation cones top and bottom. I've heard that they were made by the same guy that makes the Record Research record cleaner. They're worth checking out.
