Inside the Iso Acoustics mechanism

the isoacoustic Gaia are very good but the Townshend podiums are a whole different level better and that's from people that have tried both but the Townshend podiums are three times the cost and all I can tell you is when I put them under my speakers it sounded like I changed all my electronics too much more expensive gear. check them out, they got to try it like it or return policy, the company told me that they've never had a pair of podiums ever returned.

An alternative with superb build quality and sonic impact are the Arya Audio Labs RevOpods. Work wonders under speakers in particular. They have a range of different fittings to match all major speakers and if yours are not covered are really helpful in making a bespoke adjustment

It’s all right here:

elastomer, arranged to do what it does.

There’s a sketch of the insides but no description of the stuff.

I would be equally interested to know about the featured parts inside the Gaia and Orea. Are both the same or they are different.

From what I read, the Gaias brought an impact to most systems and the changes are mostly an improvement. With the Oreas, the differences are described to be more subtle to the point of negligible.

It would be good if someone opens up the Gaias or Oreas and take few photos of the insides.

The component parts may not have nearly as much impact (if any) as the height.  Raising your speakers an additional inch or two above the floor is bound to have some effect (a beneficial one if they weren't at proper ear level to start).
