Close. There is no such thing as absolute proof in physical science. Mathematics is all about proof. A proof may depend on postulates, and you can argue the postulates, but once you accept the postulates, the proof is either solid or not Engineering, and all other science (chemistry, physics, astronomy, etc.) have theories and do experiments to validate them. Sometimes it takes centuries to show that what was accepted is not really true. F = MA is one, that while 400 years old, and true in any case we care about, its not true at quantum levels. What 99% of the world considers as a scientific proof is not. Its about rejecting the hypothesis with high confidence. Opaque's example of 99.9% confidence is very high, better than the chance that a meteorite will hit me in the head when I walk out to get the morning paper, but there is a real, non-zero chance of a meteorite strike even with a 99.9% confidence against it. There is a reason that every graduate student in science and engineering at every university in the planet is required to take a term of statistics. You have to understand what these experiments show, an what they don't show. I've been looking, and I have seen zero science that says there is anything delivered in hi-res commercial recordings that can be detected by humans. -- Pat Farrell http://www.pfarrell.com/ _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
