IsoAcoustics Gaia w/MAGICO

Hi,

I plan to order Gaia I for MAGICO S1 Mk2.

MAGICO has closed back design with no bass port. There is no chance to listen this kind of tweak before ordering. I am afraid footers could worsen SQ because of loudspeaker’s design. MAGICOs reside on hardwood/concrete flooring  

Can someone share (real life) experience on this one?
Thx.
