why don't they get it?

Please tell me why woman or at least most don't get it when it comes to good audio gear. I was in a Florida thrift not to long ago with girlfriend when I spotted a Kenwood 8300 tuner in absolute mint condition for the asking price of 20bucks, so of course I did the the sane thing I plugged it in when everything seemed kosher I happliy made my purchase. Now all the while she can't believe that I am interested in this old and according to her, an ugly archaic hunk of junk,now all the time I am trying to educate her about good quality equiptment that was built at a time when pride and and sound prodution was an important factor. But of course nothing I could say would change her mind if it doesn't have a blue light around the volume knob and volume control she is not interested. I guess it must be the female mind.
