Magnetic Plinth
I recall my friend getting a magnetic TT plinth, which floated on air. and recently i came across one on ebay... im wondering if folks have had good luck with these? and if the strong magnets interfere with anything at all?
currently, i have my classic on stillpoints.. im just always looking to upgrade.. thanks.

Cool concept, but I would fear the magnetic fields.

Regarding you concerns about creating magnetic fields that may cause interference or hum, my understanding is that the opposing magnets on most such designs are positioned so that their magnetic fields cancel. In other words the sum of the opposing fields end up being zero, so creation of additional hum is not an issue. Of course, YMMV applies.

i mean this seems like a no brainer. i wonder why more of the industry is not more about floating like this? perhaps it is too isolating.... an object suspended in the air can still take on a lot of vibration, with no where for it to go.... where as my still points drain the mechanical energy in both directions....

Magnetic suspension designs initially appear to be an ideal isolation solution, but then there are some limitations that become apparent. It is relatively easy to magnetically float a mass in one direction (i.e. isolation from vertical movement), but try to keep those opposing magnets stable from horizontal movement and you can imagine the difficulty in maintaining stability. So most of these magnetic isolation systems actually only provide vertical isolation by magnetics and have to incorporate some kind of mechanical support to maintain horizontal integrity. This is where some tradeoffs enter the picture.

hmm, good point, i could see a 70 pound turtable flinging across the room, mid record... not cool...
ill keep my stillpoints.

I think magnetic is a great idea, Clearaudio has Been doing this for many years.

I did not mean to imply that properly designed floating magnetic platforms will go flying off of their suspensions! Rather that they generally only use the magnetics to isolate vertical motion, along with another type of support/bearing which stabilizes them horizontally. So they are in effect not magnetically isolated in all directions, usually just vertically.

Stanton made an 8005M /A table with their 881S cartridge back in the day that was belt driven and suspended magnetically.
