Twl...No doubt that "something is going on", but the question is: should the investigator be a scientist or a psychologist. Probably both, IMHO.
Some people believe in psychic phenomena, and many tests have been devised to try and prove, by statistical means that psychic phenomena exist. No one is convinced, except those who believed before the tests. However, IF someone were to discover, not that it exists, but HOW it works, some kind of electromagnetic radiation between brains, then it's existence would not be in question, even by people who lack the ability.
So, people who want to convince me that exotic power cords affect audio equipment, need to come up with some rational explanation as to how this might happen. So far the various "scientific" explanations that I have heard fall short of credibility.
