@howardlee I know this is a bit pedantic but there's no such thing as a KEF Ref 7 Meta. There's an "R" 7 Meta, which of course is a line below the Reference line. Reference pairs consist only of models 1, 3, and 5.
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?
