Have Gaia III’s under my new KEF Ref 7 Metas on a hardwood non-suspended floor. At 64# that is right at the top of their weight limit but sound is clear & focused top to bottom. Important to note KEFs came with default spikes and padded discs below them should you not want spikes. If you’re in that situation M8 screw-in pads of some ilk would be go-to up front. The disc under the spikes I would consider a design flaw. The Gaia suction pads are not much impediment for positioning but carpet slides would help should that be a big deal. Installing the Gaias properly require reading the instructions and doing it during unboxing if possible as easier with them head down.
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?
