It is only recently that I have experienced good isolation from vibration. I have spent at least 25 years exploring isolation devices, using bladders, spikes, mass, wood, cork, springs, like pole magnets, multiple layer shelves, carbon, and even active phase reversing electronics. I have sought to directly couple speakers with spikes all the way to decoupling them with gel. Everything had some benefits and some liabilities. Most could be heard to make a difference. None of these continued to impress me for very long.
The one device that has continued to impress me is the StillPoints new Ultra Stainless Steels and Ultra Five isolation feet, not the old cone devices. Basically these devices change vertical motion into horizontal motion and heat. The key thing is that you don't have to be concerned with where you want to take it. I no longer have concern with footfalls when playing vinyl and have great clarity and realistic sound stage.
