I have the halographs, 2 pair, Shun Mook mpingo disks, Brilliant Pebbles, and the H-Cat line stage with its WTC. All of these interact. I will not spend time talking about when I had RoomLens, diffusors, TubeTraps, etc. They are all gone. I have largely removed my Shun Mooks and now only use a pair of the Halographs. This was the result of my removing everything and setting the WTC for its best and then reintroducing what was removed one at a time. This all took a long time and thus I am hesitant to redo this with the resonators. I have many friends, however, who swear by them. Hearing their experiences, I don't really care whether present science can explain how they work.
