Umm ... maybe, just maybe you're the one that doesn't get it? Not being sarcastic, just trying turn the question around to get you to think deeper.
Why should more women get into our hobby? Or men for that matter? Why should they get it? Reminds me of those 80s touchy feely seminars where everybody gets it ... but did they really?
So you put on an "alleged" fantastic recording. Maybe your wife has better taste in music than yours?
Not being judgmental, just getting that people may have different tastes.
Some people get into the mechanics, some get into enjoying the product.
Certainly looking at the music industry, a lot of females drive the music purchases. The successful list of artists that cater to the coveted female 18-34 demographics disproves any lack of interest in music. Bet there is more exposure and new money made from the female populace at large than from the vintage LP collectors on this forum.
From some of the pundits here who point to the end of our audio hobby as we know it, maybe it is the small niche minority hobbyists who are anachronistic dinosaurs. Which reminds of an old saying, "Neanderthals who need to count to five shouldn't be pointing fingers at female sabre tooths."
It's a matter of perspective. And who's really at the center of that demographics universe.
