How large (or small) is the audiophile market?

Just to be clear, I am interested in the number of audiophile consumers, not the dollar valuation of the market.

Well, when I started this topic I thought it would be pretty harmless.  Who knew?  I was just curious about the size of this hobby...

I suppose to clarify, I would consider an audiophile to be anyone how cares about music reproduction enough to have some sort of playback system besides a smart phone and earbuds or an Alexa device.

When I was in college it seemed that pretty much 50% of men's dorm rooms had some kind f decent stereo.  I could count the women's dorm rooms with decent tunes on one hand.  So that would put the population at about 12.5% of students with decent music back in the 70's.

Now I don't really know anyone besides myself (and my system is pretty modest) who owns anything other than "lifestyle" products.  So that was the direction I was trying to go with this thread.  There is so much expensive equipment out there...who buys that stuff?
