Wilson Audio isolation footers

Hi everyone

I wanted to know if anyone has tried the new Wilson Audio Pedestals? It's a new isolation foot that is designed to go under a front end components such as a turntable, preamp, dac ect. The literature I've read says they're not designed for speakers. If you have tried them I would like to know what you thought and did you compare it to any other isolation feet? Thank you.
