I think the main reason for women not being into high quality audio is an asset allocation issue, not to mention gender bias. In my youth young men my age had two things they spent their disposable income on, cars and stereo.
It was my experience women loved music and enjoyed listening, but did not prioritize gear. Women turned me onto Jethro Tull and Steve Miller in the early 70s.
When shopping for gear with my wife when we bought our first house together, she was good if I wanted the big Maggies (20.1), but I did not want to go that strong dollar wise. We both have loved our 3.6 Maggies for almost 20 years now.
One thing I have noticed is that for whatever reason, more men like to sit alone and listen to music and design critical listening situations that arecealy not designed for group listening.
Given the similarity to the car hobby (I am also into cars, have owned 4 Austin Healeys in my past, not to mention Mercedes) I just think it is asset allocation by gender that is cultural.
