A happy marriage is a reasonable compromise that works for both. In my case, she can have the whole main level of the house. Decorate the way she wants, select the colors of the walls, flooring, furniture, etc. I don't care - I agreed to this.
I get the finshed basement or traditional; "man cave". I get to decorate it, select the colors, furnsihing, etc and also and most important, the HT-HIFI system. She has no say down in the cave whatsover - not even Christmas knickknacks are allowed down here during the Holidays unless she gets my permission.
For those guys who do not have the good fortune of having a man cave, then I suggest you insist on one room of your house, apartment, whatever be yours. Set up your system in that one room the way you want and give her the rest. Men are like dogs and we need a place to call our own, even if we are mated to the pack. If your woman does not agree to this more than fair compromise, then you got a problem man! It may be time to become a lone wolf.
