Another option would be the Isolation Acoustics GAIA footers. 

Some sunny day when children are playing and laughing and there’s no strife or steadily increasing crime rate somebody with excellent hearing and a really really great system will do a comprehensive review of all the various coupling and decoupling widgets and thingamabobs out there, from, oh, I don’t know, Audio Points and bungee cords and hockey pucks to Minus K and magnetic levitation and, gulp, beyond.

geoffkait,

Yes; I agree.

A shout out to Mike at Ingress Engineering.  I purchased his "rollerblocks" for my pre amp, and mono block Herron amps.  Similar to Symposium but a little smaller.  A good value cost wise and they made an improvement between a cable and equipment change. They opened up the soundstage and defined the instruments more precisely and tightened up the base. 

Will the IsoAcoustics Gaia resist the MM3’s weight (575lb/each)?
