Isolating my speaker stands

Hi all, I live in an old house that has floating wood floors. As you can well imagine, it is an acoustical nightmare. I have my Signature S2 speakers sitting on stands that are supported by spikes, even though it's a hard wood floor with no carpeting. Would I benefit from replacing the spikes with something like sorbothane pads to help decouple the entire system from the floor? I just ordered a Subdude for my sub in hopes that it will help with the bass. Any suggestions will be greatly appreciated.
