Audiophile demographics?


Why are there a disproportional number of male audiophiles?
Not sure if this is a silly question, but speaking for myself, I have never met a female audiophile.
I am sure they exist, but their scarcity begs the question as to why.
Is it merely that men have more of the "mine is bigger than yours" mentality, do men love gadgets and tools or is it something more sinister?

Using a very narrow definition of audiophile perhaps.  From what I can tell, many are fixed income :-)
@Tony1954  Could it be as simple as people who are more interested in things than in people become engineers? There are more male engineers than female. Interest in people vs. interest in things. 
I wonder how many of us followed our same sex parent into our hobbies, thirst for technical knowledge, and magazines to read.  How much does a male vs female school curriculum influence our lust for science and solutions?  And, since it was mentioned, how much money do women spend on things to make them pretty, i.e.shoe comment?
@emrofsemanon - I would bet against you. Probably much lower % - median is probably $50-75K. Demographics of audiophiles are older, many retired or semi-retired with time on their hands to play around and experiment with stereo equipment. Younger (below 50) % of audiophiles is probably very low.

Mid-upper income people are probably working and don't have much time - they may spend a lot as part of an entertainment room or home theater but never used the term tonearm in their life.
