Audio is delivered through a Focal Utopia 7.2 surround sound system. Their speakers are handmade in France, beautiful, and obscenely expensive.
The whole setup is controlled through a Crestron automation system, which can be made to dial in just about any pieces of electronics you want it to. It feeds the entire entertainment interface to a smartphone or tablet, so it's easy for anybody to get a handle on. Know how you're parents have, like, four remotes if they want to watch cable TV with sound? None of that nonsense here.
