I use two on the back half of my Wadia, and a Shakti Stone on the front over the reader. Three were too much on my Wadia and overdamped it, the Shakti was needed instead of the third one. You can see them on my system photo.
Remember though, I'm using them in conjunction with the HRS Rack, Bases and Nimbus Couplers. So what it does in my system might not work the same in yours.
