What is the purpose of your multi-zone setup? Are you using it to play music in your second and third zone? Or are you playing videos/movies and would like their audio to play in the second/third zone?
Have you taken a look at sonos? Seems like your zoned speakers are not amplified? Although I do not like denon's user interface much, but it is pretty feature and rich works great once you finished setting it up.
