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?

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.

Jadem6 is right, look at Stillpoints as well. I didn't realize their SS model can handle a thousand pound load per foot. A set of those should handle the heaviest of racks!
