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

I have a relationship with gal once got olympic Gold Medal in TaekWonDo sparing tournaments. After a while she left the big sport and got into music quite deep to the level of enjoying jazz, jazz-rock, classical and new wave. Often after listening music in car she'd always want to play same home on my system for better sound. She's got great hearing for music as well.
I helped her establish dojo and she helps me with my music media store.

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).
