The thing about the gurus, is they MUST believe in themselves. Unlike me or others, who have enough scientific background and know ourselves well enough to understand that WE are the biggest variable.
Example, so there is this GURU listening to his system, he is deep into audio, he has read all the adds for cables and interconnects and cryogenic fuses and whatever all we have all been exposed to. He has read all the scientific explanations, even if the science applies to radio frequencies or frequencies well outside the audio hearing of any human or dog or bat, so he knows there is some "science" there. Then he also knows that he can hear a difference between components, sometimes right away (that would be a real hearing thing, that would be good IMO) and sometimes he must live with this change for a long time to "discover" what he really hears. He is fine with that second theory, its science to him, as he has experienced it in the past, he has decided he did not like something after listening for some period of time, so he knows it works.
The sad thing is, he does not acknowledge how variable and tricky his ear/brain and memory interface all are, way tricker than he is. See, he does not even know "who" he is. He is listening along and all of the sudden, he "knows, understands, and believes" that that sound is "wrong" or better or not as good or the image shrunk or whatever. How does he all of the sudden "know" this, where did that thought or insight come from.....well, duh, from somewhere he has no knowledge or control of, the brain can not "look" at itself operating. BUT, if one believes that whatever thought the conscious grasps onto that is thrown up by the sub-conscious then he is a believer in "himself the GURU", and thus can quite genuinely express that he did hear that fuse or wire or whatever, and how it impacted his preference for music. They believe their preferences as thrown up by their brain, the thing they can not look into from the outside.
They refuse blind testing because they are not open enough to the fallability of their brain/ear/human body system. AND, they choose the science that works for them, and toss out the rest that does not. It is a religion, a system of beliefs based on faith (that which can not be shown true but is accepted as true), faith in ones self. They are deeply religious in that way.
