I'm trying to look at this in relation to the article. What gets young people into hi-fi and keeps them interested? If we take Schiit Audio as an example, you need to look at the intended market. These are more 'lifestyle' products for people that want compact 2 channel systems. Beautifully engineered, good specs and often compared to products costing a lot more money. Yes, you can buy a competent AVR for the same money, but for a young adult looking to drive a modern looking pair of KEF LS50 speakers (insert something cheaper if you like) or high-end headphones, I can see the appeal, and that's good for the industry.
The science over religion aspect has some grey areas. Most of us here hate the snake oil sales pitch on cables, but do you extend that to boutique audio gear? Is a $2,000 DAC bad for the industry? I'll admit, I have to chuckle when a Youtuber claims that a $2,000 streamer sounds noticeably better than a $1,500 model. Empirical measurements would likely show that the output is virtually identical. The videos can be fun to watch though, so if they generate interest that may lead to someone doing more research and getting started in the hobby. I do feel for those like
@ciedema who encounter videos on DAC weights and power cables. That can drive people away leaving them thinking that audiophiles are plain nuts.
