The HEA of the 80's can't realistically survive in 2018-forward. It's decline has been happening since the mid 90's, no surprise here. I can't imagine folks thought the over built over priced hobby was going to interest the modern Audiophile.
Audiophiles are getting out of the trophy collecting and into their listening, movies, games or whatever. I'm seeing an increase in the hobby, just not the way over the top build hobby. It's not the early 90's where the magazines pulled off that amazing revolving door of plug & play. That was insane, literally! The pitch was "My system doesn't sound right so I'll buy another component". That's pretty crazy but they managed to sucker folks into it. Now after a couple of decades of that (whatever that was), hobbyist are not buying into it anymore, why should they?
