I got this system to use 5.1 digital audio through its optical input. For the price, it is definately a good deal for a home theater system, but if your just getting it for the speaker set up, go with the Logitech z680s. The sub is not powered (it just takes left and right like all the other speakers), the remote control was sluggish, and the onscreen menu was extremely limited. The dvd picture and the sound was high quality, and the speakers were small and sturdy.good home theater system overall
