How large (or small) is the audiophile market?

The definition of audiophile is not a simple task...

 This concept is multidimensional:  I consider myself an audiophile but my purchase are made at peanuts costs... Am i an audiophile ?

I am not an audiophile if we use some criteria related to price and upgrades sum...

@jtucker very small.

Apple's dongle revenue in a year can be used to pay for every company not already owned by Bose, Samsung

I am interested in the number of audiophile consumers

that's what I wrote, if everyone buys a new speaker every 10 years, maybe 10 million people +-30%

In the December issue of TAS they report their subscriber numbers (it’s required for print magazines).  They printed 16,250 copies a month (average for previous 12 months). Total paid circulation was 14,188. There are also about 11,700 paid electronic copies

I don’t have my Stereophiles handy. Their numbers are higher but shrinking too.

I’m not saying there are 26,000 audiophiles but these numbers give some indication that there aren’t a huge number of us.

Paul at PS Audio once did some math that arrived at a population of 250k. Obviously, your definition of the target for inclusion will vary, but for high end stuff that might be close.
