I find Guttenberg's video persona (which might very well be his real personality too) to be among the nicest, most easy-going of any audiophile-world personality. I also like that he periodically have videos where he features or interviews other enthusiasts, including some folks with fairly modest systems and many folks who are not famous or established personalities.
That said, there are two factors that make me steer clear of his videos most of the time.
- The obvious one is that he buys into and parrots the greatest hits of audiophile woo-woo and subjectivist nonsense. Granted, he does it in a super-friendly, laid-back way. But he does it nonetheless.
- The less obvious one - and I truly am not trying to sound nasty here - is that even as entertainment I find his videos frustrating, because he almost never delivers on what the video's title and his intro claim the video will be about. After the first 30-60 seconds, the content is often rambling, tangential, and rarely gets to the alleged point or offers a substantive, responsive answer to the question or issue posed in the video's title. It's quite striking how consistently he fails to actually discuss what he says he's going to discuss.
Still, I can't help liking the guy, and will occasionally watch a video where he interviews a non-famous hi-fi enthusiast or where he tells an interesting story from his hi-fi sales days.
I'd never, ever take anything he says seriously in terms of evaluating equipment or helping me decide what to buy. But if I'm going to listen to someone in that mold, I'll take him a billion times over someone like Darko, who has all the same demerits wrapped in arrogance and pomposity instead of avuncular friendliness.
