Why all or most audiophiles are men?

Manufacturers, hire more women as sales reps!

@2psyop If you were married you would know how dumb you are. I get reminded all the time 

@johnwern, "all the mid century classical composers were men..." That's simply not true, there are vastly more women than commonly realized who are credited with classical compositions. The fact that few of them entered into the commonly recognized repertoire is related greatly to matters of who had access to music publishing and performance venues: men. You can't separate women's cultural roles and lack of opportunity in times past from their lack of representation in the pantheon of composers. See this list of women classical composers if interested: http://www.kapralova.org/DATABASE.htm

Thanks for enlightening me. Yes, Mahler didn't want his wife getting into composing and Einstein didn't want his wife to be a renowned physicst which put her into clinical depression. And music is regarded as a career socially less respectful field in the orient. If you see the member of orchestra in Asia, more than half are women while you see handful of women in Berlin Philharmonic. I agree with you.
But my intention was not in the gender difference in music. 
I will definitely get into the site you suggest. Thanks.
