Turntable isolation platforms


Need some reco's on turntable isolation platforms.  Currently I'm considering the isoacoustics delos.  This is another step in the battle to reduce acoustic feedback (see previous posts of mine).  I currently have TT  on a  Pangea audio rack with a rumble filter with iso feet but want to remove rumble filter and use XLR input and not RCA. All ideas are welcome for a solid platform.  GO!

I think if looks are important, Adona gives a lot of bang for buck.  Otherwise, I would not spend big bucks.
Are you sure it's acoustic feedback, i.e., sonic degradation from the volume of the music?  Or do you mean isolation from footfalls and the like?  If it's the latter, a wall shelf makes a huge difference IMO. 
It's definitely acoustic feedback.  If I rest needle on record and turn up volume I get rumble.  I then had a friend apply pressure to rack and the rumble stopped.  I need to isolate TT better
