It’s been noted upthread that there are increasing numbers of manufacturers, that some shows are well attended, and that this must be proof of growth of interest in audiophilia. I would add to this the attention that the companies with the really big bucks are paying to sound reproduction. Apple has Spatial Audio, and Amazon has their various home products for pairing with Amazon Music, assorted sound bars, etc. Now the natural tendency here will be to dismiss most of this (Some of us may be interested in Spatial Audio ) as not worthy of Audiophile/Serious discussion. However it indicates that there is a market for better sound than bog standard ear buds. If there are several million people out there investigating better sound, certainly some percentage can be ensnared by the whole enchilada.
Clearly the industry needs to move beyond our demographic, the aging white males with retirement portfolios who are willing the buy lots of products so that we can continue to enjoy music that was released half a century ago. In doing so, our demographic is a negative. They don’t want to project the image that if you go down this path, you will turn into this bald fat old guy sitting alone in his listening room.
However the reality is that most of the new generation of listeners they are seeking are sitting alone in their bedrooms, probably multitasking while listening to music in the background. Good luck flipping that group into people willing to spend 5 figures for a component .
