Plug and select CD works just find, that is how my second zone works.

Also, if you have an RF remote, like a Harmony 890, etc., you can use the zone volume control on the Denon to control the volume (and source) of the second zone. I do this so I can control the volume and source to the speakers on my back deck without going to the amp for the second zone. Just set the volume once and forget about it.

P.S. NOLAT, what setup are you running? I have not heard many Axioms yet, and the Denon 4000s have my interest peaked so I may beg for a listen?
