Do magnets and electronics mix?

Ever since Kurt Vonegout first wrote about magneticly suspended furniture I have been in love with the idea. When S.A.P. came out with the relaxa isolation base ($500) My interest was rekindled. My first thought was that I could make my own for about $100. The only thing that bothers me is what effect rare earth magnets will have on the electronics... tubes in particular. I can not believe it would not fowl a stream of electrons. Perhaps the exponential decay of force over increased distance is enough buffer. Any thoughts, fella's? I like the idea of zero contact under my components. I wonder how many magnets would be required to lift my 200+ lb altec vott's and what havoc that would wreak.

Ed-sawyer...Magnetic levitation in three axes is possible: it is used to "suspend" the active parts of gyros and accelerometers used in missile guidance systems. It is an ac system, where movement of the suspended part towards a point where it would "touch down" changes the impedance of the coil that is providing suspension force in such a way that the current in that coil is changed, and its force changes so as to push the suspended part away. A set of coils provides both axial and radial support of the suspended part.However the available forces are much too small to be useful in this audio application.

If you really want a vibration-free mount, and cost is no object, check out www.halcyonics.com. I have "at-work" experience with their Mod-1M model, and it really works.
