I heard a couple of the D'Agostino's running a giant pair of Magico speakers at Axpona in 2019. They were set up at the end of a deadend hallway surround on 2 sides by glass, and they made it sound like a live concert. It was one of the best sounding setups at the show, and the most amazing part was that it was in the back of a hallway, not even a room. Yea, crazy expensive, but sound amazing.
