if I may jump in, I think BB's point was that the advice varies even on the same topic with the trust this, then don't trust the very same thing. We tell people to listen, then tell then they can't possibly hear differences!!
so in reading your post (which seem to have taken very serious tones lately)you state:
"I would also take the opinion of someone who does or has been involved in controlled science over someone who is only providing their personal, subjective opinion."
well, that would include you, and even then scientific data provides one measure, but as we all have different tastes and hearing abilitiies, should we trust what they hear and like? Our opinions are all subjective.
how do you "scrutinize" personal taste "for accuracy"
