Turntable isolation for bedroom floor

My Clearaudio turntable has magnetic bearing in the vertical direction - its benefits are limited to the reduced friction & wear; it doesn’t do jack to reject footfalls. In fact magnetic suspensions can sometimes make footfalls even worse (e.g. Clearaudio’s magnetic bearing arms). However a properly tuned spring suspension can work wonders. E.g. I have a SOTA Nova that’s almost immune to footfalls. Though I haven’t tried them, Townshend sells spring feet & platforms that get good feedback - I’d look into those.

And honestly I'd toss out those magnetic feet. 

@millercarbon  that's very interesting, thanks for the suggestion. 
How about placing the one rack with the turntable in the sand...?

@mulveling  thanks for your input. I'll certainly try removing the magnetic feet. Maybe try sorbothane hemispheres...??

The difference of course is that turntable magnetic suspension isn’t intended to decouple the platter or provide any isolation. 

@geoffkait  what would you say is the purpose of the magnetic feet? When I had stand mount speakers I found they improved the sound significantly...
I know you can't really compare isolating speakers to turntables...
