Query: Great sound and easy to set up

This is an excellent value. It was easy to set up for the first time and use. While it is described as a mini system, it does take up quite a bit of space. I would not describe it as a shelf-system, unless you have very large shelves -- it will not fit into a bookcase. It has a neat remote control, accepts 5 dvds and has a raduio and cassette player -- I still have a considerable collection of cassettes, so this is an attractive plus.
