Magnetic levitating turntable shelf-opinions?

I have seen two different types of magnetic levitation shelves/platforms for turntables, etc. These would not be hard to make and incorporate into a custom component rack system I'm currently working on.

Does anyone have personal experience with this type of product? Specifically, if you are using it for vibration isolation of a turntable are you satisfied that using such powerful magnets near a cartridge is not interferring with the cartridge performance?

For you scientists out there the magnets used are neodymium and yes, I realize how dangerous they can be to work with.

Thanks for the input,
Patrick

From an engineering standpoint, these types of mag-lev designs are not truly isolated in 3-dimensions. More like 1 dimension for the designs I've seen. and, it's physically impossible to have them independently floating in 3 dimensions. It's provable from a science standpoint or just try it with 2 magnets and you will see this easily. The floating shelf platforms are really no different than just 4 springs. In fact springs may be more isolated than the maglev stuff. The designs I've seen have vertical rods to keep the shelf aligned. These function to connect the two shelves, nearly rigidly, or at least with as much force as keeps them separated magnetically. Sure they look neat but do they break any new ground, technically? The answer is no.
