I am looking at buying the Denon 3805 reciever. I have lots of input sources however and would ideally like a couple more audio inputs. The only way of getting 13 or so inputs means spending serious money on something like the Denon A1. My question therefore is what happens if I connect a digital source to one of the optical inputs and a separate analogue source to say the CD in. Is there a simple way of switching between Dig and Analogue to effectively give me the extra inputs I need ? Thanks for any help on this.
