I had Gaia’s on top of concrete blocks and the sound was pretty awesome. The bass was deep and tight, soundstaging and transparency was impressive. Due to the tweeter height I switched over to some platforms that are always said to be a step up from the Gaia’s, but to be honest the Gaia’s on concrete blocks, even with a the added tweeter height, was pretty pretty good. Would I switch from the Gaia’s knowing what I know now, probably not.
IsoAcoustics GAIA
I have IsoAcoustics GAIA II isolators installed on my Sonus faber Liuto floorstander speakers on hardwood floor. I expected some improvement and I got it. Bass is cleaned up and tightened. Stage became more clear because isolators removed a curtain made by unfocused, scattered bass. Floor and sofa vibrations almost disappeared completely. And... WAF is good. GAIAs passed my wife's inspection. Is there anybody with some experience regarding those isolators?
