Isolation platform - Gingko vs Mapleshade

I am using Symposium and Critical Mass systems platforms.

Sounds like a plan, Miner42. You might also research what Aires users have, and maybe what they've tried.

None of suggestion with the possible exception of Minus K actually address all 6 degrees of freedom which is actually required for true and thorough isolation. Even Minus K IIRC disengaged the twist isolation so that it wouldn't interfere with turntable rotational motion. One method that will get you pretty close to the sacred 6 degree of freedom isolation is a combination of say springs or airsprings or Ginko balls and set of roller bearing assemblies like Dhurama II. That way you achieve very good isolation in the vertical direction AND very good isolation in the HORIZONTAL and rotational directions.

Wow i did not know that!!

I have the Gingko (though I do not use it a lot). It definitely gets a few things right. For a non suspended TT like Aries it will do the tricks that a suspension does, meaning a very black ground and airy clean imaging. Thankfully it doesnt screw up the PRAT while doing so. My only complain about it is the use of Acrylic platforms and base. To me acrylic always sucks out some life from the music. The Gingko also does that a little but not a lot. You will never get such clean black backgrounds and grainless imaging from a mapleshade wood platform.
