"Believe" is a very dangerous word, because it takes the matter of whether you are ignorant or not out of your hands.
If you choose not to "believe" something that turns out not to be true, congratulations, you're a justified skeptic.
If, on the other hand, what you choose not to believe turns out to be true, the English word for that is "ignorant".
Better one should say "I don't perceive it". At least then you're off the hook and still telling the truth.
High-end audio is always on shaky ground because of the all the silly crap that some goofy people believe,
but it's not all silly crap and it's not all goofy people.
If it matters, I let the recording rig warm up for a couple hours before getting to work, and that's as close as I get to "burning in".
