as far as the owner manual, it just tells you the basic information, i did not think it was too bad but it does not describe the full potential this receiver can do.
I have mine connected through a switch via Ethernet. My house is all hardware wired with CAT 5 cable. As soon as i plugged it into the Ethernet port, do not do what i did and plug it into the denon link, it worked perfect. Internet radio was super clear and i had a bunch of radio stations to listen too. I like the internet radio, it gives me a lot more choice of music, i am just goofing off at the house or outside.
The one thing i wish the Denon would do, or it might, i want it to show my album art work on my cds in iTunes or what ever source i need to put them into. It aslo needs some form of visulizer on the screen during music playback.
just my opinion but its a great receiver and i still will work to get the most out of it.
