"Geoffkait, I specifically left out the Acoustic Resonators for two reasons, they are not Tibetan bowls, and they are no way near as effective."
They are ALL bowls, including my ceramic 1" bowls. Calling them "Tibetan bowls" I think confuses the issue somewhat. I think that eleven bowls would certainly be better than say three or four. Did you have eleven of the Tchang Acoustic Resonators? Has your system changed. Lots of variables involved.
"For me the question still remains "how can resonators improve the sound?"
Have you read any reviews of the Tchang Acoustic Resonators to see if their mechanism of operation is revealed. Do you know how Mpingo discs work? You are a reviewer, right? I thought reviewers were supposed to be able to get to the bottom of these things.
