Pros: ARC - Zone 2 - Airplay - YPAO
Cons: None yet
YPAO - Very easy to setup and run. After config, noticed it was lacking overall bass. Went into the manual setup and had to change the speakers settings to small and raise the sub output from -8.0db to +3.0db. It basically muted my sub.
Network - I bought a Netgear WNCE2001 wireless adapter for $30 and it works great. Took a bit to get it to recognize my router but has been solid since. Internet Radio is awesome. You can Bookmark stations through a web browser and than you have a custom playlist. AIRPLAY is flawless. I sit on my patio and stream my music from the iphone to Zone 2. That is priceless!
ARC - works great with my Sharp LC-52LE640U. It turns on and controls the TV. Also the built in WiFi on the set has netflix and it also works great. No need for an optical cable.
Zone 2 - The easiest setup I have seen yet. Turn zone on and set input. Thats it. From the iphone can access most of the important features. Now my kids can watch a movie inside while I listen to music by the pool. The Niles speakers really sound impressive even with internet radio playing.
Dialogue Lift - another great feature for those times when they talk real soft in a movie. Just turn it up a few notches and no more struggling to here the dialogue.
Overall, I must say this is a big step up from what i had. You will not be disappointed.
