Having a dedicated room for stereo was a prerequisite to marriage for me. It might seem a tad bit harsh to do something like that with the love of your life, but the way I looked at it?
I saw what happened to my Step-Dad's stereo system (which he absolutely loved listening too when he was a bachelor) after he married my Mom. I saw the same thing happen to many other folks I grew up with who got married. They basically lost their enjoyment/passion/hobby/happy place. I wasn't willing to accept that with a lifelong partner. She knew full well that I had been in this hobby since I was 8 years old, had varying systems for decades before I met her and that I had always been knee deep into it. Since she didn't want a stereo system in the LR (Where have I heard THAT before? *rolls eyes*), she agreed that a dedicated room was acceptable.
We have been happily married for 18 years, this past May.
