Nicely put.
YouTube clips certainly do not all sound alike.
I'd go further and say that a well recorded YouTube video will tell you a lot more than any written subjective account ever could.
The difference between any impression gained by the written word and that of hearing it for yourself is fairly significant.
You could say a similar thing about hearing a recording in the studio and then reproduced on CD or vinyl etc but there's nothing like hearing something for yourself.
Presumably, when it comes to YouTube, on a pair of decent headphones.
