IsoAcoustics Gaia feet on Oracle Delphi turntable

what @cleeds said... the delphi is designed to have its wonderful floating suspension do the job... it takes some skill and experience to get it set up right, orient the weight underneath properly and so on ... 

I installed Gaia III footers on my trusty VPI HW-19 Mk. IV.  They did seem to improve the isolation and thus the sound.

BUT (and it is a big one), you have to be very careful about the threaded inserts into which you screw the Gaia footers.  The bottom of the Gaia footer is shaped a lot like a suction cup.  So it is going to really stick to the surface on which it is set.  And the material of this bottom part of the Gaia is a lot like sorbothane, which in itself is very, very sticky.  
 

Put these two characteristics together, and the Gaia footers really and truly do grip very powerfully whatever surface they are placed upon.

Twice—when lifting the turntable—I pulled the threaded inserts out of the bottom of the turntable frame. I had to reinsert them and re-glue the inserts. 
 

So, be warned and be careful.

If you really do want your turntable to stick (as if glued down) to its mounting surface, use Gaia footers.

I once tried a set of Gaia III as replacement feet for my Clearaudio Ovation (about 45 lbs). I didn’t care for that so much, so I got an isoAcoustics Delos isolation base. That worked so much better. In summer 2013 I upgraded that Ovation to an Innovation, which is too heavy for the Delos I had. I changed to a HRS R3X isolation base, factory tuned specifically for my Innovation. I still have that and it works great. I am now thinking about upgrading my Innovation to a Master innovation. At ~140 lbs it will need a new isolation base, or at least new feet for the HRS I have. I am giving serious consideration to a Minus-K base for that.
