Dave, you're averse to many tweaks, which I totally get, but make an exception for the Shun Mook Diamond Resonators. Can you say why?
The caveat was proper, expert installation. I've seen the Shun mook guys at work previously in one of our CES rooms and then a few installations at client's homes, in every instance they worked as promised without coloring the sound. This is only with their discs I have no experience with their footers or other products.
