That is an interesting question.
I have been building good audio systems for about 50 years now. Video is a very recent addition.
During my 30 years in our Grand Forks ND home, and the during the six years I was in Canada my main system was in the basement, although I had a good system in the living room also, I cold enjoy by the fire.
There were significant funds in these systems, and I was the only one in the family who used or listened to the basement system.
I suppose basements being dark they would have been ideal for video. I have to say I have really enjoyed getting out of the basement, and have really enjoyed the light and views from this space.
When I put my main space together two years ago, the design started sometime before that, I wanted to make this a very versatile space.
My prime criteria was that it be a superb audio space with good video capability. Most of the time the video display is off. I don't watch movies by myself. I do watch opera though. I have CD, SACD, DVD Audio workstation, LP and 78, DAT PCM F1 and reel to reel tape, two and four track with Dolby A and B, dbx I and 2, cassette with Dolby B, C and dbx 2. So it plays everything I have collected over the years. It also is a museum to a degree, and presents older technology at its best and in the best light possible.
However the really nice thing is that because of the video aspect the rest of the family just love tis room. My wife, children, spouses and grandchildren just love it. My eldest daughters husband is a real movie buff and he calls it the best movie theater in the world.
