Basic anti vibration? Cones vs pods? Is there "good enough solution"?

+1 what @stringreen said - I tried steel, glass, wood and Brass/Bronze on my granite tiles.

Steel and glass sounded a little "brittle" and "harsh"

Wood was a little "mellow" compared to the Bonze/Brass, but much better than the Steel and glass

The Bronze/Brass cones provided the best sound for my system 
- more dynamic with improved details and clarity over the wood
Hope that helps - Steve

You wouldn’t have the problem in the first place if you’d only thought ahead and placed the appropriate size springs under the house during construction. That’s what Shannon Dickson did in Hawaii, you remember him, he was the author of Bad Vibes! - the seminal article on vibration isolation for audio components that appeared in Stereophile magazine in 1996. Think ahead. Maybe you can backfit the springs. Lots of laughs. 🤗

No matter how much you have in the end 🔚 you would have had even more if you had started out with more 🔜

geoffkait, it is more stable to hang your house from springs than to sit it on springs. If the houses center of gravity is not right in the center of the situation it will bobble to one side or another making everyone inside seasick. David Fletcher modified Edgar Villchur's design this way when he created the SOTA Sapphire back in the late 70's. You can't get seasick is a SOTA. You would construct three or four adjustable height towers and hang a reinforced concrete slab from the tops with steal cables that wrap over pulleys at the top then head down to dampened springs of some sort at the base of the towers. 
If we can find an environmental benefit we might be able to get Google of Bill Gates to build us one.

A good enough solution for me was Herbies sliders under my Proac d15's. No adverse effect and you can easily move your speakers around. I've had vibrapods but they seem to work better on amps, etc vs. speakers. Always wanted to try more advanced footers but cost was an issue. I'm now looking to change to Proac D2's and stands - not sure what isolation will be necessary for stands. 

Is that what skyhooks are for? 😳 Does Herve Villschaise approve of them? Everybody and his brother has been using tension springs and bungee cords like forever. LIGO the project to detect gravity waves uses compression springs but whatever floats your boat as it were. I’m not sure I’d go back to the 70s for my technology. 😬

As for stability it helps a lot if you know what you’re doing. Low profile springs of the correct spring rate are extremely stable under most loads. And much easier to implement. Hanging stuff with springs is very tricky and inconvenient.
