IsoAcoustics GAIA

Possibly, but obviously superior engineering than a soborthane foot.

The beauty of the gaia is their sturdiness keeping the speaker solidly anchored. With soborthane there was times while I adjusted the speaker placement that I came close to watching a 6ft 214 lbs speaker come crashing down. Now it is sound and safe.

@baylinor yeah they are very study and well engineered, I was hoping to love them.

They probably work for most speakers, but in my system I got a better soundstage and smoother sound with the carbon fiber pucks from Amazon and then a round piece of heavy duty hard rubber I had in my shop, I thought a had used sorbothane rounds but I forgot I just used some 1/4" thick rubber... 

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.
