If she isn't into the gear, is she into the music?

The quality you seek in a partner is that she respects the
things you enjoy, whether or not she personally likes them. When
the home gets unpleasant, you find yourself home less and less.
When you're listening to the hifi, she knows where you are -
home and out of trouble.

Oh, I'm so lucky. She's played (violin) in classical orchestras and not only does she like listening, she has a better ears than I do. But, alas, not technical (at all).

Most women I know today could careless about gear and even music.. well, maybe a little music to provide a little background noise. Most women today are into/on their phones day and night. They seem to enjoy talking and texting over music.

"Ok, can you turn it off now? My show is on."

You rememdy that by not ever allowing a TV in your listening room. I am a problem solver........

My wife likes music but could care less about audio gear. She likes it easy to use and not too loud.

I am having success getting her to listen to a wider variety of music in my music library these days than ever in the past by displaying my music library and currently playing information on the big screen HD TV in my family room using PLEX app on Amazon FIre TV feeding into my two channel A/V system. Its much like the format used by the music channels she likes on our cable TV feed. SHe has no interest in my audio system otherwise other than knowing that I get a lot of enjoyment out of it.
