Gosh, these threads take a life of their own. Engineers, Physcist and Muscians! I guess it's left up to our ears to decide. I don't know the science or really care, but I have used Sistrum and still do. I notice more detail without brightness but more important more musicality. That's what I listen for. Energy is going to find the Earth to ground itself anyway, the Sistrum seems to increase the efficiency of this transfer which increases the accuracy of the read and lowers the vibration on the boards. Now don't take this as science because I prefer the PychoAcoustical approach as in reference to the 73' Hamm AES studies. I simply like what Sistrum does for my system. My only regret is that I don't have an infinite amount of $$$ to do it all.
