I know it's been posted by somebody else also last week but here is the story about this sound system.
It's a bit long but I enjoyed watching this.
Wow, after watching that, I'm thinking that's probably an amazing sounding system. Custom designed huge room with no parallel surfaces, and an angled ceiling modeled after a Japanese concert hall. 3 Floor to ceiling line arrays with near sota drivers and all active crossovers. Also dipole radiation with carefully calculated backwall distance. Then you have matching surrounds. With 24 subs placed all around the room, I bet the bass is smooth, tight, and extended as ever. Listening distance is 25ft back, and hearing classical concert level dynamics at that distance probably gets you closer to that live classical sound than 99.9% of systems out there. Even the surrounds look ~15ft+ away.
It actually seems like a really carefully planned and implemented based on objective criteria. Guy seems really logical and actually seems to have good knowledge. Definitely some snake oil in there with the turntable/cables but his logic for those seems somewhat grounded. He notes that expensive cables don't sound better and that it's just about distance and guage. Turntable he admits doesn't make sense, but he does it because he enjoys building and upgrading it.
I think it would be very difficult to make a system that sounds as good as this in a typically sized room. A room that size (ime) with careful acoustical planning is probably impossible to match in a small room, even with perfect Genelec One speakers.
