Why did I get married?

Put your jacket on and tell her you are going to a bar. Suddenly, she may "enjoy the music".

Mutual respect. Give and take. Some days you have to go with the flow. My wife and I are best friends. If she asked me to get rid of my system, I'd do it. Our relationship is worth a hellova lot more than twentyfive grand of electronics. So turning it off on occasion is no big deal.

There are about 10 guys in my audio group. Half of them are lucky in that they have a room to themselves- a man cave, where we can listen to music with our friends, or alone, and the wives usually leave us in peace. We can turn it up and listen to what we want.
So, try to take over a room to have to yourself and let her have the rest of the house. She's got it anyway, so you win.
I realize this is not an option for everyone, but it is truly the best one unless you have a wife who is also passionate about the music.

I like the idea of putting your jacket on and say you're going to the bar, but that might lead to divorce and after paying your attorney you won't have any money for your stereo hobby anyway.
It has been my experience women have better hearing than men and women can hear higher frequencies than men do. Maybe there is something about your system that isn't allowing your wife to enjoy music the way you do. Ask her what she thinks of the sound. I am sure you will get an honest answer and she will probably be right.

My wife (married 34 years) doesn't mind very loud music (NO, you cannot have her - she's mine) but have some issues with certain music I listen to (contemporary/modern, Indian Classical, progressive jazz etc.). I try to avoid music that makes her nervous (I play it when alone).
