My wife wouldn't choose to have any of my gear, but does appreciate the sound. She enjoys listening as long as I keep the volume down and she can reach, stitch, or play on the iPad. The system is in parallel with the home entertainment setup because we have a small house and no extra rooms. Our "office" is a box in the coat closet and a MacBook. No listening room for me.
If she isn't into the gear, is she into the music?
Are you with someone who enjoys music? Would this be a quality in a partner that is or has been important to you? It just seems there are few couples I know who are both into music later in life. I just can't imagine how it would be to here, "Ok, can you turn it off now? My show is on."
