All of the receivers I've seen have just one 5.1 analog input. I have a DVD-A DVD player now but I'm considering adding an SACD/CD player. Do I just have to switch the cables or is there another way? I just saw a picture of the Denon 5803 and it looks like it has 2 5.1 analog inputs. I really don't want to spend $4000+ to use both SACD and DVD-A.
