We figured in a previous thread that there less than a million audiophiles in the US and of that group only a small number care enough to post about it on internet sites.
This estimate is probably off and the number is a lot higher, imo. The younger audiophile is a "home theater" guy, with a HT setup, spatial headphones, etc. I know quite a few of them in my city. They view audio as a multitasking system for their music, movies and games. Their setups tend to sound shockingly good and in many cases may beat the daylights out of some of the $$$$ channel based purist systems around here.
The older lads here probably have little to no idea about the above mentioned, play games, etc. Purist stereo rigs my be a dying breed, but, the above mentioned is not. If these uppity audio brands don’t repurpose themselves a bit, they will be closing shop soon enough.
The fact that AV forums have skyrocketing memberships and sites like Agon have dwindling membership should be initial proof.
