Went through the same thing with my Ex Wife. She hated the big speakers I bought and put in the living room without telling her. I do and did see her point, but she never understood or appreciated my love of audio equipment at all and in a way she brought it on herself by not letting me put in the 5.1 speakers in the living room that she actually bought me. My new girlfriend understands that the speakers and the stereo are not negotiable. I've learnt that... Buy your stereo equipment before you move in and if you do... Buy it BIG. That way if you downsize she'll be appreciative. My new girlfriend asked if she could replace my current KEF R900 with something smaller. I said sure... and showed her a pair of KEF Reference 1. They're only bookshelves but the price seems to have silenced her for now. Also a bigger TV does wonders in shrinking speakers.
