We have two whole threads on the topic of reviewers, YouTube- Reviews, Chats, and other Content and Good audio reviewers and ones to stay far far away from. But that might be a bit much to wade through, lol.
Since you mention DMS, he is the producer of the Abyss channel’s content on YouTube. You may find that entertaining. I personally watch PSAudio (Paul McGowan), The Headphone Show, formerly Resolve Reviews (Jonathan Park and Chrono), ’DBS Tech Talk (David Sylvia), Currawong (Amos), Wheezy Tech and The Headphone Experience (William Murdoch). For more YT Tyll content from days gone by search YT for the defunct Home Theater Geeks, episodes 69, 91, 92, 133, 154, 172, 243, 279, 297, 325 and 370.
