i use Adona and decoupling footers, or active isolation.
the problem with 'uber' racks is the 'sunk' cost, and then they are impossible to sell or ship once you have them. footers have the same or better performance, and are flexible and priced more reasonably.
if i was looking for the best rack with decoupling tech, hand s down it would be Artesania only. equal or better in performance but won't break the bank.
