I'm upgrading my receiver from a 10 yr old Sony surround, even before Pro-Logic, to a Denon 1802. My speakers are going from some Technics CBR77 3way towers to Axiom M22s. I cant wait till it arrives. My question is I dont have a dedicated Cd player I've just been using my 2 yr old Philips Magnavox Dvd player for Cds. Does it make that much difference to have a dedicated Cd player or not?
