At first I wondered also about the room, then I read the article and realize that this gentleman is no novice. By the way, his equipment is way more expensive than half a million. He most likely spend more time in front of his gears than behind them so unlike most of us he doesn’t have to be swapping cables every week. Rooms can be very deceiving. The acoustic doesn’t really care how nice the room looks. Do a quick search for Michael Framer’s listening room and also Dr. Floyd Toole’s. You will be surprised. I am sure a lot of experts have visited his room and helped with his installation. I hope he is enjoying it.
