I'm a bit skeptical about this YouTuber for some of the reasons/impressions listed here.
That said, he's right when he says that making this video goes against his own channel's "brand." So, he gets points for that.
Something about the OCD label does describe some things I have gone through and have now pulled back from. So, points for that, too.
For those here actively hating on him, I'm not sure where the anger/passion comes from. Perhaps he struck a nerve? Otherwise, why so heated?
I'm with @mahgister about seeking sound quality with every tool possible, and I think he's right about the many ways that can be accomplished without the consumerism and expense endemic to this hobby.
