A simple truth in audio is that everything one does and thinks will change the sound, or will apparently change the sound - some are 'real', some are not. The crazy ones most likely are in the "not" category - but I have encountered "crazy" effects: doing something which makes no sense at all, at the time, causes a change in sound - sometimes only after years does it all come together and the chain of cause and effect reveals itself more clearly.But there isn't the time in the universe to prove all audiophile superstitions right or wrong. Nor is it actually possible to prove them right or wrong (as I was saying in another thread). All you have left is to weigh up the likelihood of whether a "pet rock" being promoted by a person of dubious technical or philosophical qualifications, will change the sound even though its effects cannot be measured by any test you can devise.
So, audio people are well used to "crazy" stuff - because, well, some of it isn't so crazy after all ... the hassle is that separating the crazy but real, from the really crazy, is not always trivial.
