I have a 7.1 surround system for Movie Night. I purchased the Ray to upgrade the Samsung TV sound so I could hear clear dialogue from the day to day TV shows. Absolutely cremates the sound from the TV. Brilliant!! Amazing frequency output. If you want to upgrade just your TV sound inexpensively, this is the master above all. Not near the 7.1 system I have for movies, but unreal for day to day tv sound....
