... would i have to firstly run an ethernet lead from my Pcs router to the Denon the output to the controller via the Denons ethernet output ( im guessing they have one ) to the controller.
If Jason's previous answer doesn't tell you what you need to know, you might want to try restating the question.
Unfortunately I don't totally understand what you are asking based on the quoted question. Are you talking about running Ethernet cable from Router to -> Denon to -> ?Controller?
Apparently Jason is much more perceptive than I am. If so, just take his answer.
