Isoacoustics Gaia II on what type of speaker platform?


I'm interested in the Isoacoustics gaia footers for my speakers.  The room is on a suspended wood floor with carpet.  The carpet is too thick to use the optional carpet cups.  Any experience using a granite or maple platform in this situation and then having the footers sit on the granite or maple platforms?  Positives / negatives?

Believe there is some confusion about the Isoacoustics products and their proper usage.  The thickness of a carpet bears no relationship to the use of the carpet cups.  The carpet cups are not to pierce the carpet and lodge in the sub-flooring.  They merely stabilize the Gaia II footers so that the footers do not move on top of the carpet.

I know this because I use the Gaia II and carpet cups with my ATC SCM 40 active floor standers and they work in conjunction wonderfully.

I hope this assists you.
