Hi, I'm fairly new to home audio and would like some help connecting my DVD player to my receiver. I am using a Toshiba SD-4800 DVD player and a Sony ES STR-DA2ES receiver. My DVD player has analog 5.1 output, which I am currently using. It is connected to the receiver into the "multi channel input". I am thinking about buying a digital coaxial or a digital optical to connect the DVD player to the receiver. Can anyone explain the difference between the two? And which would give me the better theater sound? Thanks.
