Isolation feet under diy rack

Photon
Thanks for the kind words.
The reason for trying to build another rack is that I want to move all electrnics but the monoblocks to the side and create a wider stage between the speakers.
My room side can't accomodate tall racks so I wanna build a wide lower rack.
Currently the racks are on the wooden floor with no isolation and I think I need some kind of isolation

You're most welcome as a guest but the racks are located in Israel...
I will research all recommendations posted here so far.

For now I bought a set of 4 stillpoints ultra ss sold here on A'gon. The rack is still in its design stage and I think I'll go also for soundcare superspikes and have them tested one against the other once the rack is completed. I'll keep you posted...
