+1 for Adona.
plays above it's price in build quality, look and performance in a solid rack. owned it now for 6 years in the context of a cost-no-object system. and the pieces are modular so it can be expanded easily. you could buy longer legs to add shelves, or cut the legs to shorten it.
if i wanted a decoupling rack i would absolutely buy the Artesania; but it's more in the $6-$13k price range.
for my needs i would rather use footers and active isolation for each shelf and piece of gear.
