Favourable 7.1 Receiver with 4K upscaling

Edit 2.5.13: After extensive testing I came to the conclusion that one should hear normal stereo music via standard stereo speakers. the purchase of a 7.1.-receiver So really worth it! Implementation of zone 2 is, as described below, ok. I can not judge whether this was better implemented at Pioneer, Yamaha & Co. However, unfortunately.
------------------------------------

I own the device for a month now and am absolutely satisfied. For me in particular, the following features were buying decision:
- Network Connection: works very well, I can, for example, via DLNA reach my network hard drive.
- OSD: total operation via the TV is very convenient. However, I have to confirm that the menu at Onkyo is a bit strange. To this end, submit a half point
- 7.1 / zone 2-way: The amplifier can respond boxes up to 7, either 7.1 or 5.1 and Zone 2 with stereo speakers. I have my old stereo speakers connected to the Zone 2, which also works mediocre. mediocre because the Zone 2 has only limited functionality (operation difficult, less adjustment). In addition, the Zone 2 speakers must be connected to small clamping sleeves (1.5 mm² was already difficult). this half a point deduction.
- Video upscaling to 4K: I have it set so that each video signal, is no matter where, upscaled to 1080p, and that works very well! I can only recommend that you look for when purchasing that the AV receiver also includes these video signal-processing option, which is for example. in the price range Yamaha receivers in this not the case!
Overall, the upscaling (Yamaha in the price range it has as I said not, Pioneer only to 1080 p, and not 4 k) was the reason why I chose this Onkyo.
- Pro Logic II: works very well
- Control over Android App: nice gimmick, but the remote control or a universal remote control can not really replace

a total of 4 stars from me and a buy recommendation!
