The concept is that an all in one system takes away a lot of variables. And you get decent sound. Just the way the designer likes it for his type of music. But your taste will most likly differ and if you are educated enough, you can come up with a much better set of performance parameters by choosing a different manufacture or mix and match different companies products. If you are not educated enough or don't demo the equipment in your system, then you may very likly come up with lesser sound quality.
