Isoacoustics Gaia II on what type of speaker platform?


I'm interested in the Isoacoustics gaia footers for my speakers.  The room is on a suspended wood floor with carpet.  The carpet is too thick to use the optional carpet cups.  Any experience using a granite or maple platform in this situation and then having the footers sit on the granite or maple platforms?  Positives / negatives?

what speakers do you have?
Believe there is some confusion about the Isoacoustics products and their proper usage.  The thickness of a carpet bears no relationship to the use of the carpet cups.  The carpet cups are not to pierce the carpet and lodge in the sub-flooring.  They merely stabilize the Gaia II footers so that the footers do not move on top of the carpet.

I know this because I use the Gaia II and carpet cups with my ATC SCM 40 active floor standers and they work in conjunction wonderfully.

I hope this assists you.

mboldda, my speakers are Vienna Acoustics Liszt.

I recently tried GAIA II footers w/ slate slabs under them. They really worked to add great depth and a floating 3d quality to the imaging... But I have Harbeth 40.2 speakers, which have a resonating cabinet type design and the footers made the speakers to lean. 
 For what it’s worth, I tried two other speaker footers and they all screwed with the tonality in one way or another...but thats harbeth for ya. Nothing worked as well as the Herbie’s Audio Labs threaded Decoupling Gliders on the stand. 

jriggy,

Thanks for the note.  I have tried Herbie's and liked the sound with the speakers spiked directly to the subfloor better.  Go figure, you never know until you try something.

Yes. I would think with carpet that a spiked footer would be the way to go. I have a pair if Magico A3. They come with stock spikes and pads or you can get Magico’s APods, which are also spiked. But I have hardwood floors and because of where my A3s are in the room, I was concerned about brushing up against a 100 lb speaker and inadvertently knocking a spike off its pad. So I looked for a different foot both for safety and acoustic purposes. I got the Isoacoustics Gaia I feet. I love them. Very stable and have a suction grip on the hardwood floors. Acoustically, good. How much better than stock points and pads. I am not sure. But what I am sure about is that for my purposes above, the Gaia I feet are a net positive. 
I too tried the Herbie's decoupling gliders, and preferred my previous spikes better.  The Herbie's softened the mid range and high end to an extent I didn't care for.  I now own the Isoacoustics Gaia I, and couldn't be more pleased - pricey, but well worth it.
I put my speakers on Gaia’s on top of thick maple cutting boards and felt that I got quite an improvement in resolution and imaging over the spikes that I used previously.  My listening room is in a basement with a fairly thick  area rug over a concrete slab. Speakers are AltaAudio Rhea’s. Never tried the carpet cups.

My experience, too. I recently installed Herbie’s giant threaded gliders under my four-post Sound Anchor stands for PMC IB2i, which are 95 lb monitors. I’m extremely happy with the results. My flooring is engineered hardwood glued to the slab. I previously spiked directly to the slab (before the hardwood was installed), then spiked into Herbie’s titanium glider cups. His glider cups were far and away better than any other cup I tried, including the ones from Sound Anchor. The big threaded gliders are better yet--and much better than the small threaded gliders, which I also tried, at least for my application.

By far the biggest insight: the height of the woofers from the floor has an astonishing impact on bass clarity, and hence everything up the chain through the mids and highs. I mean very, very small adjustments--a half-turn of each threaded footer, or less--altered the sound, once everything else was set in placement and the speakers were perfectly level. Get that woofer just a touch too low and the midbass thickens; get it just a touch too high and the bottom thins out. Surprised the s**t out of me! Woofer/floor interaction is little discussed but man, it’s important. The Herbie’s are threaded all the way to their low-profile base, so you can really dial in the height.

The IsoAcoustics were on my radar, and I even had the option to audition with return privileges, but they would have raised the woofer up too high, so I passed. No doubt they are excellent in the right situation, however.
I bought 2 cheap granite worktop savers and placed them under the Gaia.  This works brilliantly. It really transformed the sound, particularly tightening the bass. 
Just a thought:
I'm wondering if a thick (2"-3") maple block would sound better than any type of stone that has been known to smear sound? I'm guessing one won't know until they try it.
