Damping the binding posts would reduce vibrations conducted from the speakers into the amps by the speaker cables. Cables may be more or less flexible for side-to-side motion, but are very stiff for motion along their axes. I've found it helpful to support my cables with stiff paper cylinders that are damped against their own acoustic resonances. The cables are dressed with gentle curves so that speaker vibrations are not transmitted directly into the amps. Every little bit helps, so I'm not surprised by your findings.
Materials used as acoustic dampers have dielectric properties. Teflon sounds good to me, but others do not care for its sonic character. It is an excellent vibration damper as long as you don't put it under severe compression (it flows slowly). I use Teflon thread-seal tape to damp the cable lifters and AC plug blades in my system.
Cotton also sounds good, and some who don't like Teflon find cotton is an excellent dielectric. Cotton batting can be used for acoustic damping, but is not as easy to work with as Teflon. You can find 100% cotton batting in fabric stores that sell quilting materials. Be careful, as a lot of cotton batting has polyester in it.
