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.
