I've made my decision to save the $170 and go for the Yamaha.
I compared the rear panels and realized that I wouldn't use the RS232, PC-In, Zone 3 Pre-outs and some other Onkyo extras.
I also Downloaded both Android Apps and both have their pros and cons but both are very nice. It's too bad the Yamaha doesn't have a simple remote control function (Up, Down, Enter) like the Onkyo.
I guess I will never know if the Onkyo would have looked or sounded better.
Plan on buying in a couple days, any comments to change my mind much appreciated.
