IsoAcoustics GAIA

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. 

Slight aside to the topic, though I do have Gaia's.  Installing was made significantly easier using a couple of small inflatable liftbags about £10/$15.  You still need somebody to steady them, but nobody is having to take the weight.

@bigwave1 Any firm opinions as whether to spike or not spike the Gaia's on carpet?

Definitely spike. The Gaia’s work best if they are firmly anchored. Your soundstage will improve when you install them. 

I just bought a pair of Sonus Farber speakers and haven’t put Gaia’s on them yet, but when I put them on my KEF Reference 5’s, they made an instant improvement in the presentation and the bass.

Vote for with the carpet spikes.  I ran one with one without and switched L to R channels, same test I did with and without GAIA's.
