"I just get blank stares when I talk about my hobby to women."
Include men in that too! Blank stares all around!
However, there are exceptions. I met my girlfriend by helping her buy a system. The most interesting thing is that she used to listen to music while doing other things, but now, if the stereo is on, she doesn't want to do anything, BUT listen. She said that she never knew that music could sound this way.
She's somewhat odd though. I have a pair of home brew speakers using Newform tweeters (45 inch) and she loves the way they look. The Newforms are not pretty to most people.
Heck, even I don't think they are attractive, but they do sound good!
As for other people... Everyone who listens to my system is amazed at the clarity, but the conversation never goes beyond that.
As a whole, women are less interested than men. I think that when women look at a large speaker they see a good place for another chair.
BTW, I used to work for a drycleaners and one day this guy came in and talked for an hour about clothes. I was never so bored in my life and it dawned on me how people felt when I spoke about audio. I've kept my mouth shut since then.
