What's great about Pete Thorn's demos is that he explains the controls of the products, and gives thorough demonstrations with musical examples of how each control works. And the context is highly professional, so you get very fine musical examples of how to use the product, and can see whether a piece of gear fits your workflow - or playflow, if you will.
That's why he's a favorite demo guy, and why places like Vintage King Audio and manufacturers hire him to do these demos.
Not all of the products float my boat, of course - I thought the fractal settings were way too watery sounding. But when he tests a piece of gear I think would work for me, I often buy it. So as far as I'm concerned, that's pretty effective advertising.
Also, Pete's audio quality in the demos is high enough that you can put the video up in a studio with good monitors, and hear details.
I like the dude who did the power supply shootout, he's a lot of fun! Though I'm not sure what his point was intended to be -- maybe there was no point, and it was up to the viewer to reach conclusions, but I did think the audio quality could have been a little better if we were supposed to hear details.
The Fractal AX8 sounded impressive in that demo.
