Any Advice for those Listening to Youtube Reviewers?

I agree. Be careful of ulterior motives as well. This is really not something to put much stock in, do other research.

It seems most people will never get that audio is not about the gear pieces but about how to learn to listen...

Yes must learn to listen not only to sounds which is acoustic basics but also to music,classical,jazz,world; and no, our "tastes" must be educated by ourself not by reviewers...

I’m a noob but I enjoy Hans on YouTube. He seems factual and neutral. 

I think Sean at Zero Fidelity for what he review does a good job. He doesn't review DAC's, turntables or tube amps but what he does review his assessment are pretty accurate, just listen carefully.

FWIW, here is the list of the on-line reviewers ordered by the number of subscribers. It does not suggest the quality of contents they have presented but give you some idea on their popularity. The ones highlighted are those I listen periodically. Some of their verbal description of the gears' sound traits they review are spot on. Some often gave measurements and how that entails to the actual sound. Some gave rather technical details to the components under the hood. I appreciate the time and effort they have put together for each show.
