Thankfully the wife allows me free rein in the living room ... since we met at a classical concert she is very much on-side on the importance of music in the house. We don't have a telly to take up space either which means the hifi is happily allowed to dominate the room.
The one time she put her foot down was my request to block up the door to the living room to accommodate a pair of Tannoy Autographs (the only way it could be done). There was still a side entrance from the kitchen but meant going through two extra doors (and the kitchen) to get there.
