Yep agreed with your folks, he is just one reviewer and not the gospel truth per se. I do respect him a lot for his reviews and graphs, though I've disagreed with some of his IEM reviews before (eg Audiosense T800). I guess at the end of the day, the bigger question is, do your tastes align with his, do you still enjoy your gear no matter what he says? That's the more important thing I feel.
This hobby is so subjective, we all have different sources, different ear anatomy (affecting pinna gain), different hearing health, and we use different volumes (Fletcher Munson curve), we listen to different music genres, some are treble sensitive, some are trebleheads etc.
