Anybody have both Herbie's Cone/Spike Pucks and isoacoustics gaia's

My Spatial Audio X5's sit on pieces of granite which sit on top of carpeting with a concrete floor under all of it. Am very happy with the performance I'm getting now but was thinking of getting some isoacoustic gaia's for my speakers because of all the positive feedback. Never heard of Herbie's audio products before I started in on my research of isoacoustics. I'm wondering if there spike pucks do the same thing as the gaia's do? There pricing is attractive. So I was hoping to hear from someone who may have had both and could give me there feedback.

Perhaps it has to do with the speakers that are being tested with these products.
I have the Herbie sliders I use them under all of my spikes, including component stands. They allow me to move the stands when needed.
And, I did have them under my speaker spikes until I purchased the Focal Sopra 2’s. The Gaia 1’s under these speakers way outperformed the Herbie sliders. The soundstage widened, deepened, bass tightened etc, etc,

I also have the carpet spikes under the Gaia’s.


I tried the Gaia 1's under my ATC SCM100aslt's about a year ago.
Unfortunately I didn't find them an improvement over the basic furniture felt sliders I was using previously. I returned them.

Yesterday I installed some Herbies giant stud gliders (fat dots with gliders and screw in studs attached).
From first listen it was obvious the Herbies footers were an emphatic improvement.
The whole soundfield has more clarity and floats more free of the speakers which disappear more as sound sources. Positioning of instruments in depth is better defined.
The tone and texture of voices/instruments and particularly transients are clearer and more realistic. There's more delicacy and decay to sounds.
It's like a layer of intermodulation distortion has been removed.

Unlike the Gaia's they allow easy movement/repositioning of the heavy SCM100 towers and only raise the speakers 20mm. They are also inconspicuous, which I like.
I use the regular sized gliders under my Skylan stands. Very nice product, no desire to change them.
