Is the idea of audiophile listening a dying concept as boomers die off?

Audiophiles are born by hearing music on a system of someone who has better equipment than he has. We are certainly no longer in the era of audio stores on every street corner, but so long as there's a saving remnant there's no reason why things might not turn around. It's the height of foolishness to think that the latest turn is the last one. One phenomenon that bucks the trend is the renaissance in headphones caused by computer gaming and portable devices. Sort of like dinosaurs evolving into birds but it is a move in a particular direction.

@OP - Yes. Check the demographic at hi fi shows - male and old!

Greed is the answer.  They seem to have  forgotten that you can't have an affordable flourishing market for Prorsche, Ferrari and Lexus, unless you have a flourishing market for VW, Fiat and Toyota.  Otherwise, it's all on borrowed time.

As The Frogman always says, The Unwashed Rule.

No. 
not in my experience.
