There's only a coupla youtube channels for audio I bother with....mostly AH, ASR and Erin's Audio Corner but I'm still more a reader overall. Generally the subjective only reviewers or "experts" (often just salesmen of a sort) can have some dubious advice, or if they're videos of a system playing that's worthless IMO, but I'd mostly I'd not waste my time with most of the "audio" youtube channels, like I do with most of the magazines/blogs/fora too. Just way too much noise out there.
Sounds like you've done well getting to where you are now....congrats.
