I agree with KeithR. There was obviously a lot of thought that went into the design of the room. I guess its fair to be critical, but I would have a hard time believing that anyone would turn down a chance to listen to that system, much less own it.
The article was also a really interesting read. I got the impression that to Mike this was more than a hobby, but a serious part of his life. He sought out experts and made decisions based on his own habits so that function and form were both addressed in the design. CD Player right next to your chair, build in CD/LP racks, under floor cable runs, in wall piping for turntable air hose. . .etc. That's a little more involved than a few echo busters and bass traps. I also liked the fact that he mentioned multi channel in the article since it showed that he's looking forward, not just staying put.
I'd pay to hear it given the chance.
