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

Guys,

I stayed up most of the night doing some experimentation. These are my results:

Note that my music room has a carpeted concrete floor.

Moving my preamp and turntable into the garage which is next to my music room provided no audible improvements.

Placing the turntable on an air bladder platform provided no audible improvements.

Some tack welding, several solenoids, a car battery and a 3/4" piece of MDF levitated (pretty crude setup but it worked) and a lot of effort in leveling this device provided no audible improvements.

Conclusion:
Back to basics.

I appreciate all the input. I believe that John clarified what conditions the levitating platform would be useful in. TWL, I have a suspension turntable and can attest to your practice of coupling to a solid surface as having always worked well for me. I do think the solenoid system could offer some real benefits except if it got unplugged. :~(
