Our simplest bookshelf speaker system is nothing more than two wireless, powered speakers. No amps or streamers needed. But don't misunderstand—it is a true Hi-Fi stereo system, in every regard. It has a high end streamer built in, along with the ability to connect to your TV over HDMI, your gaming system, and even an optional turntable. It is simply our easiest system to set up and use, everyday.
