Upgrade rack before Vibration Control?

I am using a salamander twin 20 rack, and have a universal player and DAC that could benefit from vibration isolation. I could upgrade my rack (only candidate is steve blinn design) and then start playing with aurios, stillpoints, symposium platforms and the like. My question is would this be worth the expense? Would the salamder rack work just as well after I applied the vibrisolation control that works best for me, or would there be any sonic benefits to getting the more sturdy and spiked steve blinn rack first?
