I can't get it to work via HDMI off my Apple TV...manual says I can't too.
Haven't had a chance to try it yet, when I do I will post it. Sounds like its pretty slick. I have set up the network, downloaded the firmware upgrade right away, and set up the HD Radio. ALL very easy and worked great...the radio stations are overwhelming! May not need my play list but I just aquired a former DJ's back up hard drive w/a Terabyte of music so I am set w/a lot of crap dance songs and versions of the chicken dance

Read my post above on my comparison, for me the Marantz sound a lot better.
In addition to me listening I had the General Manager of the Best Buy store with me and the Magnolia store sales associate. Both of them it was the first time they had a chance to A/B/C Marantz vs. the Denon and the Onkyo and they couldn't agree more. We all 3 were objectively listening to all machines and it was very clear to all of us. We listened to the Denon first (what I thought I would buy), then the Marantz, then the Onkyo, then the Denon again.
We were listening to a set of B&W floor standing 600 series, CC6 Center, and DiPole rears w/the sub turned off. These were the closest sounding in the room to my speakers...a stretch but the best they could offer. I knew mine would sound better...
The TRON cycle race chapter offers some great stadium acoustics w/voice, cheering, and fireworks. Awesome voices w/the MC and a crackly voice. Then of course the motorcycle racing with some great crashes. I felt was a good overall listening sample
Good luck with your purchase you can't go wrong w/either.
