Speaker Isolation tweaks ?

Hi everyone,

I want to tweak my bookshelf speaker(Revival Atalante 3) isolation.So my speakers have small isolation feet attached to the speaker, which in turn just rests on top of my speaker stand. So technically not attached to the speaker stand. These are sand filled stands with adjustable spikes, resting on a hardwood floor. I currently use dimes underneath the spikes to prevent holes in my hardwood floors. So would something like the IsoAcoustics Gaia isolators work, by replacing my existing spikes with the Gaia isolators ? seems these are to be attached to floor standing speakers. If so, the Gaia iii is for speakers less then 40 lbs, but do you include the speaker stands ?

I kind of want to stay away from adhesives. Don't want to stain or mark up my speakers.

Anyway maybe people can share their thoughts on how they approach speaker isolation  with bookshelf speakers on stands.

Cheers
