Love to hear from current owners or past users of Isoacoustics Gaia footers.

I have GAIA I's on my speakers and I'm very happy with them.

Which footers did you replace? Your provided spikes? Thanks. 

I was thinking about getting the Gaia II, but the cost is 600.00 plus I would need the spike cups at an extra 140.00.  It also looks like the spike cups aren’t long enough to use on my thick wall to wall carpeting.  Last thing I want are my 115 pound speakers sitting on top of the carpet.  

I replaced the stock footers. I have Stillpoints under the rest of my components. The GAIA's improved bass articulation and allows the speakers to disappear better. It's not a night and day difference. You have to hear them in your own system to determine if they're worth it to you. In my system I submit the GAIA's are a much better value than Stillpoints when I consider packaging and positive impact on sound.
