I put my Rockport Capella II on a pneumatic anti-vibration table, similar to that under the Sirius III, and experienced considerable improvement in term of background blackness with no negative effect that I could hear.
My friend put his Technics SP10 MK2 on a Minus K and got similar improvement in background blackness, but I was not familiar with the system so couldn't tell whether there was any negative effect.
However, the Minus K is not self leveling, so if the CG of your TT is not exactly at the centre of the platform you need to add some weight and move it around the platform to level it.
