Reducing Resonance Between Speakers and Stands – Need Advice

I have the ISO 200 stands, sitting on the plate of Monoprice 24" stands. When I assembled the Monoprice stands, I put 1/4 inch Neoprene in between all joints and screws, and another layer on the plate under the ISO stands. 

All of the above…add mass to your stands or upgrade to a more structurally inert stand. Mate the speaker to the stand with sorbothane sheeting (AudioQuest sells a sheet that can be cut to treat a pair of speakers) and if budget allows, invest in Gaia feet.  If on a carpet, IsoAcoustics has carpet piercing spikes that go under the Gaias.

The cheap version is Monoprice Monolith stands, play sand filled baggies, and Blu Tack mounting putty.

Townshend are superior to Isoacoustics Gaia

Could someone explain why a soft material like Blu-Tack or Sorbothane sheets might be better between a stand and a speaker than an acoustic isolator like IsoAcoustics? I’m still new to this hobby, but my intuition tells me that something soft like Blu-Tack would mellow the sound, while something like IsoAcoustics helps the sound detach from the speaker without introducing distortion from stand vibrations.
