I'm researching in looking at replacing an existing onkyo 5.1 home theater receiver that died after 10 years. I have Genie DVR, AppleTV, Bluray Player hooked up to a TV at parents house. They want a new a receiver, maybe replacing the speakers later with in ceiling at a later date, I think the existing wall mounted speakers are still working ok. One of the requests was to be able to have the surround sound going at the same time as headphones(not yet purchased). Would I need to get something that has a zone 2 receiver and hook headphones to zone 2 or do I need get some external box? Would like to get a receiver that is about < $500. Any thoughts or recommendations would be appreciated.
