If you read Robb Report (aka Michael Jackson's favorite magazine) you will see ads from a fair number of high end manufacturers, including Wilson. They also feature stories of people who have very expensive home theater installations, sometimes a stereo system, and often other collections of wine, cars, boats, watches, etc. The settings are almost always extremely large, elegant, and, for most all of us, over the top residences. We were talking with a piano dealer who sells very expensive grand pianos ($100K and more). Many have gone into homes where the owners do not play, but want a concert grand in the living room because of how it looks. And, of course, only the best. I believe that most of the people with grand homes and matching stereo installations will have consultants who do the installation. They often have to compete with interior designers and spouses who want a certain look, and not to have speakers in the "wrong" spot in the room where a certain piece of furniture has to be. Of course, they can always build a separate room just for the stereo.
