When I purchased my SR7009 in April, I had two issues out of the box. The first issue turned out to be thumbnail artwork in iTunes exceeding a specified size and causing AirPlay to choke. Got that figured out and AirPlay has been stable for months now. The second issue appeared to be a faulty volume control on the remote (and flukey volume control on the iPhone App and iTunes as well). I decided to live with the second issue as well.
Fast forward to a week ago and AirPlay has decided to become unstable. The network connection to the Marantz is fine (wired, not wireless), and internet radio options work when AirPlay does not. The SR7009 ceases to appear in the AirPlay list as an option, or when it does appear and is selected, the AirPlay connection dies. Or it may work for a few songs, and then die. Song selections don't have the artwork issue. Powering everything down (laptop, iPhone, SR7009) has no positive result. Other AirPort sources and clients remain stable and usable. The network connection is solid.
I now ALSO noticed that the volume control issue that I've always had with the remote (and iTunes, and iPhone app) ONLY happens in iTunes. All other sources behave completely as expected, including internet radio. The symptom: changing the volume setting results in the volume randomly drifting all the back down to zero or to some lower number (even though I'm firmly pressing the + button). The volume level continues to slowly change even after I let go of the button.
Resetting the SR7009 does NOT fix the volume control problem (over about 10 resets in the last few months). I know if I call Marantz, they will tell me to reset the unit to fix the AirPlay intermittent issue. This is highly frustrating as, once again, I'll lose all of my Audyssey settings. Given problems with DM equipment handling AirPlay filling the forums, I don't know that even an equipment exchange will fix the problem. Anybody else experiencing this? Any advice?
