Well, a lot was covered. Of course, this wasn't a bash modern gathering. After all it was held at a show full of vendors promoting their latest wares. Unfortunately, I left the seminar before it was over because it was almost closing time and I hadn't been to every listening room. It paid off though, if I hadn't left when I did I would have never made it to the GamuT room and listened to the RS5's that made the day for me.
Back to the seminar, the talk quickly went to vinyl and the recent NY Times article about increased sales. One attendee mentioned that he thought young people don't care about this stuff as much as we did when we were their age. He said that he has an $80,000 system and that his teenaged daughter is allowed to use it. Yet when she has friends over they go to her room and listen to music on a portable unit. He just shrugged. Others pointed out that most of the vinyl is being purchased by younger people. My son, who get's it, almost jumped into the conversation.
At the 2013 Show Art Dudley said that "It's like we gained the world and lost our souls." "Some of the newer gear [sounds like] a skeleton without any meat on it's bones." This theme was touched on in the '14 show when as I said earlier, a panelist said "Maybe we need a little more distortion." (paraphrasing). I think some of this may coincide with the sound quality issue Mr. Guttenburg was getting at in the article posted in the OP.

BTW, there's actually a mistake in the '14 article, it wasn't all men. There was one lady sitting in the back of the room right next to where I was standing.

It is my understanding that these Virtues of Vintage type seminars have taken place at several Audio Shows around the country and always seem to be well attended. There is interest and merit in the discussion. It shouldn't annoy anyone where another chooses to see value. Both modern and vintage can coexist as many here on AK already know.
