Check out (google) Moon Zero Gravity Magnetic Levitation Shelf. The shelf is suspended in mid air using 2 shelves with guide pins and magnets opposing each other. I think it's hogwash, being 500.00 but maybe you could make your own. Happy listening.
CD isolation platfroms
I'm considering an isolation platform for my Ayre C-5 XEmp. I recognize that my current equipment stand, the Salamander Designs S30, is far inferior to the more elborate equipment stands availabe but it compliments my Mac electronics quite nicely. The Ensemble Zobro isolation platform is at the top of my list but I'm looking for other suggestions/alternatives. Thanks in advance.
