Here's to the temperate, the gentle, the moderates in audio

Nice additions.

One thing I especially like about some channels (E.g., A British Audiophile, Hans Beekhuyzen) is that they always open the hood and can discuss what is happening in the design and parts. I come away with a better understanding of some of the reasons a product may (may) sound good. 

Not that this kind of internal analysis is necessary to explain what is good or bad about a product -- I learn from those who don't do it, too -- but I advance in the hobby when the presenter incorporates well-grounded technical knowledge as it could apply to what I might hear.

Wow...thanks hilde45!  One of the best posts ever.  Inspiration to be more objective myself.

Hans B !

I have found Shane over at aussieaudiophile to very informative, humble and a worthwhile YouTube audio reviewer. I have learned quite a bit by watching OCD Mikey's videos. He freely gives out valuable information from which I have learned quite a bit.

This thread seems to have gravitated toward Youtube channels rather than dealers/manufacturers,  but let me throw J.R. Bosclair (WallyTools) into the list. He's a great example of the kind of people who make this hobby enjoyable.
