I own a few production studios and have lots of high end audio equipment in my media rooms and am very picky and hyper critical of artificial soundstages. That said, I was watching a few episodes of Elementary and CSI Miami on Hulu and the spatial sound stage between the 4 speakers is outstanding on the Pro. I have heard every tablet from Lenovo that claims to have "surround sound" and the Pro blows them away. In a quiet room, I kept stopping the Hulu because the right and left ambient sound effects sounded so real, I thought they were coming from another room in my home. Sounds like a 5.1 surround sound is happening from the front sound stage of the iPad Pro.
