IsoAcoustics Gaia vs the Titan series

I have Sonus Faber il Cremonese speakers.  They have been sitting on a concrete floor covered with laminate.  But, I am moving them to a true hardwood floor which has a basement beneath.  I have been told to get some isolating "footers" to maintain or improve the sound.  IsoAcoustics have been recommended.  I note that they have two series :  Gaia and Titan.  

Has anyone had experience with these two series and can comment on the sonic differences?

Thank you.
