A few very inexpensive tweaks to experiment with that have yielded significant audible improvements for me are:
1) place small hardwood blocks between your Vibrapods and the equipment chassis. Experiment with various hardwoods - maple, teak, walnut, etc. although I've found Zebrawood to be the best for both tube and SS components. Use three wood block/Vibrapod combos per component. You should be able to get 1-2' of hardwood boards inexpensively at a local lumberyard or hardwood specialist that you can cut to size - about 1"x1"x2".
2) Attach Dynamat sound-deadening material under the under the particle board shelf. Also, sometimes called Dead-Mat can be found at auto parts stores and is used for deadening metal vibrations when installing speakers in cars. It is a sheet of tarry material backed with aluminum foil and works as a very effective, inexpensive constrained-layer damping material.
3) Put 3-5 lb weights on each component; I prefer brass but most anything will make a difference and reduce/change component resonance.
4) Finally, if you don't already have spikes on the bottom of your rack, consider adding some. Inexpensive brass cones are available from Parts Express in a variety of sizes.
If you can't get scrap hardwood blocks contact me and I'll send you a few extra I have at no cost.
