Doesn't the head unit still have to decode an analog signal? A digital signal helps give the head unit precise info of what sounds to route where. Analog signals force the head unit to try to figure it out. I am no expert. It reminds me of Dolby surround vs. Dolby Pro Logic. Dolby digital was the better option but if all you had was an Analog signal coming in, the receivers would do its best to simulate surround sound using pro logic.
