I second Adona who make excellent racks at a fair price.

If you want a rack built to your exact specification and that is a bespoke piece of furniture check out BSR Woodworks.  http://www.bsrwoodworks.com/furniture.html
Far less painful in the checkbook as well.

If you do go for solid tech, feet of silence under the rack for sure would help with isolation.

There's also the Townshend - seismic isolation stand?
Perhaps a better option is to get something you like, or BSR custom to something you like the look of on the internet, and put Townshend seismic corners under it?

I am having a two tier low level rack built for my system out of a metal frame and mesquite wood locally sourced. I have incorporated tuned mass on springs in my design. I am trying to keep it low, like when people place an amp on an isolation platform in front to not get in the way of speaker imaging - but also not have long cable runs.

Harmonihyllan…translation is harmony Table.  The owner created these with the philosophy of the suggested surface for Linn LP12 was originally IKEA Lack, from Linn, “a rigid lightweight shelf”  

from peoples opinions I value and trust, these shelving systems are revolutionary  

many indicating a lesser component on these units outperforms the upgraded component on an “basic” Quadraspire rack.  Well that’s pretty impressive for sure.
