I am brainstorming ideas for my dorm room audio system. I just don't think I'll have room to go with a surround sound setup so I think I can live with a nice stereo for the time being. At first I was looking at stereo preamps, because recievers appear more cheapish to me. But preamps can get quite expencive once you add in the price of the amp. So I am toying with the idea of getting an integrated amplifier. But I don't understand... What are the differences between an integrated amplifier and a reciever?
