If you really want to make a big improvement in the sound of your speakers get the Townshend podiums, everyone on the audiogon forum that has tried both has said that the ISO acoustic Gaia were very good but that the Townshend podiums were on a whole different level better they isolate vibration down to three hertz so it doesn't go into the floor and back into the speakers and your equipment and also it gets rid of the vibrations in the side walls as well, biggest improvement I've ever done to my system, It's as if I had upgraded to more expensive electronics, they're double the price of the ISO acoustic Gaia but much better and well worth it.
