Stillpoints - snake oil?

Stillpoints are best used under speakers. Then if you’ve got plenty of dough, try them with your electronics. 
I’ve found they work magic with my Focal speakers on a suspended carpeted floor but less so with my Simaudio 700i amplifier or CD/DAC. 

Jim, thanks for that information. Understanding the problems vibration creates in our audio system there is no reason to doubt that these devices do work as designed. 
Listen first to decide if they improve what you hear in your room.
