OK we compared RR-888 to RR-777 and the 888 was more affective. Using a more powerful power supply [3.5W] made the affect even more noticeable.
When unplugged during demonstration the sound stage collapses, F'n amazing IMHO. Orientating them N.to S. also made an improvement over E. to W. go figure. Well our magnetic fields go N. to S. that is why.
This is NOT subtle. Yes $685 is not inexpensive. The end result is that there are zero components out there that can bring this affect for $685.
Going to try [4] units. My customer has two and we will use all of them , N,S,E and W. Yes I sleep better and just so relaxed.
