How many people on this forum who drank the "Science" Kool Aid and were disappointed will it take for you to understand? 10,100? Most of the discussion on these forums here are subjective. What’s wrong with that? If I buy a new power cord, DAC, speaker or amp, I’m willing to share what I like and dislike about that component. I don’t want to get into a metallurgical or some other such discussion to defend my purchase. Now if someone were to tell me that the connectors tend to fall off of that brand of cable, I might find that useful information- provided they have evidence.
If you go to a movie, you might tell your friends that was a good movie or a bad movie. Do you get into objective, defensible suppositions about the cinema photography, or length of scenes, etc? Or if you say that movie was fast paced and had lots of action, do your friends expect you to quantify that and benchmark it against another movie? Probably not unless you are in film making school.
Why is it that I can watch Danny’s videos? He does measurements too. But since he has been in the business and designs and builds products, he knows something about of which he speaks. He can explain why and how he makes measurements and then does teardowns to help explain why a product should sound good or just average.
I research before I buy. Having been burned decades ago by the low cost, "giant killers" I stay with the more established reputable brands. Does that mean I always get the best component for my money? Perhaps not but Caveat Emptor applies today just as it did a couple of thousand years ago.
