"audioman58, a long time ago I had Sony likepole magnet feet and later a platform from Italy much like what you are talking about.

Such devices behave just like springs.The Sonys were best as they did not slide to one side. They were about the size of the Stillpoints Ultra Fives.

I don’t like spring isolators."

i appears there’s a lot of folks who disagree on the dodgy subject of springs and isolation. You know, the thousands of Vibraplane users, not to mention Minus K, Townshends iso stands, in fact almost all iso platforms are spring based in one form or another. As well as the many university labs who employ bungee cords or similar springs for isolation. Even the project to detect gravity waves LIGO employs spring based iso systems. Of course, it’s always possible to implement these systems incorrectly or ineffectively. C’est la vie. Isolation is part science, part art. In the special case of maglev devices it’s not that they act like springs, it’s that there is no physical pathway for vibrations to get to the component. It's levitation. As I said earlier the slippery interface of opposing magnets results in a small pathway where the top plate, by necessity, comes in contact with one of the stops.

Have you tried Vibrapod Cones?  They work well for me.  I have them under my Herron Audio gear.  At the price, the Vibrapod Cones are a cheap experiment.

Thanks to all. The Vibrapods look most interesting for the $$.

I prefer Stillpoints as a first choice and Symposium Rollerblocks and a second choice but they are more expensive than Vibrapods.
