happy-sad balls from Arbor Scientific. Throw away the "happy" balls. The "Sad" balls absorb resonances amazingly well. They squash down, so nothing is needed to hold them in place. All you have to do is drop one to see how effectively it absorbs energy. They hit the floor and stay there, no bounce - apparently the energy is all dissipated as heat. I have not been able to find any source for the raw material.
Your homemade tweaks?
Having just read bgmyers thread on isolating cables and some of the excellent ideas our fellow audiogoners shared, I thought it would be great for us to compile a listing of all the innovative alternatives and their uses we have come up with to tweak our systems in lieu of buying them from the pricey manufacturers.
I'll start it off with having used tennis balls as isolation devices under components.
