You can also buy sheets of Sorbothane now, which can be cut and placed strategically in your rack. I know some people dont like the squishy stuff, but I personally have had great luck with it under my Tube equipment. I use the Audioquest Q feet under my pre amp and DAC-both Tubed. Works great.
Great idea on the Dynamat by the way. You can also get a similar material from 3M from music direct and needledoctor. I am using this at the bottom of the metal stands for my speakers, works great.
