IsoAcoustics GAIA footers: impressions


I have Spatial Audio M4TM speakers which were spiked to the thick carpet in my room.  I got the GAIA footers with the carpet spikes this week and got them installed today.  They are fiddly as hell to install, requiring a narrow needle-nose pliers to cinch down the nuts securely. 

I have been listing to my system for a few hours with them installed and from the get-go, the SQ improvement was readily apparent. There is an enhanced vividness to the music with more pronounced leading edges to musical notes and a more life-like decay to the notes that makes the sound more engaging.  I am very impressed with the SQ improvement which is far from subtle to my ears.  I previously auditioned the SVS footers and they clearly degraded the sound of my system. 

These footers have garnered lots of praise in the audio community and at $680 for them, it was an expensive tweek, but my ears are really happy with revisiting familiar recordings and loving the sound ever more than before.  I am aware in reading reviews that a fair number of folks trying them were not impressed, but Music Direct and others permit a 30-day money-back trial if they don't work in your system.  At any rate, it seems appropriate to share my impressions of them with you folks as they are quite amazing in my system.

I initially liked the Gaias under my Zu Zu Definitions 4 spkrs. But switching to Arya Audio Revopods showed them to be a tad colored and one-note in the bass. Gaias went back, Revopods stayed. 
@spiritofmusic   How much do they go for? Would you use them under components also? Thanks.
About £600/set of 4. Not sure how accurate that is, email Arthur at Arya Audio.
Designed as a universal footer, so components and spkrs.
The contrast to Gaias was one of the more fascinating ones in my time in the hobby.
In isolation, the Gaias seemed only positive. Sound warmer and more forceful. However only on A/B w the Revopods did negative comparison arise. Revopods seemed more bass light, but within a couple of songs it was apparent this was truthful and the Gaias were imposing their character.
And hence my conclusion was, Gaias were coloured.
My Holy Grail in audio more and more is natural warmth w no impediment to speed, tonal discrimination and timbral accuracy album to album. Any change that imposes a signature on my sound is out (a reason I may change my spkrs at some point).
So, on tt isolation, Minus K out, Stacore in. On component/spkrs footers, Shun Mook Diamond Resonators and Stillpoints and Gaias out, Symposium Acoustics Rollerblocks and Arya Audio Revopods in.
@spiritofmusic   Thank you for your helpful and detailed response. Your experience is encouraging me to do the same comparison, though on my amps.
I am using these inexpensive isolation pads under my Don Sachs' tube amp and I sense a bit lower sound floor to the music, but it might well be "confirmation bias."  At any rate, they are worth a try.
