@millercarbon That was a really nice, graduated ladder of listening growth -- the audiophile's bildungsroman. Another
poster here with really great ears also uses YT, but not to evaluate
anything in an absolute sense; rather, he does what you describe (I
think), namely to "see in" to the system on YT, to grok its personality.
Right. There’s no such thing as evaluating anything in the absolute sense anyway. All we can do is evaluate relative. That’s why its so important to be willing to change things. The biggest waste of time in audio is to drive to a dealer or show or friend or whatever and listen the the system and not change anything. Which is of course what everyone does. What you must do instead is have them change something. Anything. Almost does not matter.
Easiest and maybe best is to bring along one of your interconnects. Ask to compare to one of theirs. Then you hear what was in the system, yours, and theirs. Three comparisons! Or ask about the power cord or IC in the system, what do they have for less or more, and try that. Seriously. Almost does not matter what it is. Point is the minute you hear one thing change like that you immediately get a handle on the whole system.
All you can really hear by the way is the relative difference between the two power cords. There’s no such thing as an "absolute" anything. Its all relative. All the same, its a tremendous advantage to listen and compare. Total game-changer.
That’s the real reason why when I have audiophiles over I like to remove the cable elevators. Or turn active shielding off. Its not to demo the elevators. Its not to test the listeners. Its to give them the chance to hear and learn.
To me its shocking how few people try these things. But then given that is the case, its no surprise the number who never advance past that second intermediate level, can’t find any value in YT videos. These things go hand in hand you know.
Another one, whining and blaming the room and setup for not being able to evaluate what they heard at a show. As if there is some reference room somewhere we all use, and only the show room is different! Stalled out at Level II....
