Best current footers for preamps?


To isolate unit from any table/support vibration?

I agree with @arsh, I've been using Edensound's TerraCone footers (w/ point-receivers) on my VPI and it's made a big difference. Sound is more detailed, better dynamics, better bass. Dan offers a no-obligation 60 day trial so you can demo with little risk. 
it all depends on the rest of your system.   I use Stillpoints, but even tomato cans make a difference.  Try everything 'till you find the magic for you.
