Isolation feet under diy rack

Looking at your very fine system begs the question: is there anything deficient in the rack system shown in your system description? Is a matter of organization/ergonomics or do the racks shown transmit too much floor vibration with their existing footers?

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

I have a low wide rack. The assembly sits on a wood floor. It's base starts with bearing type isolation, mine is Arios but Stliipoints would be better. Then I have a sandstone slab which the rack system sits on. You can see the whole breakdown under my system tab.

From what I've seen on the market, there aren't too many choices of footers (which purport to have anything in the way of isolation characteristics) that will support the kind of weight you're talking about. The Track Audio isolation feet are about the only thing I recall that say they both isolate and support the kind of load you're talking about. Otherwise, most rack footers look like they just change resonant characteristics rather than really isolate. Herbie's Audio may sell some footers that would work as well. You'd need to compute the load each footer would bear and contact them to see what they'd recommend.
