I wont speak to reliability of onkyos I had one and had to return it. But I can tell you I own a pioneer now and I kinda well hate it. I have an SC-1222K, there are just so many little things you would never pick out of a review or even know to ask about that piss me off about this thing.
1 it takes for ever to get up and running, 2 the software is confusing and senseless and there are so many whacky decisions. They have an app for smart phones to control the device, but the thing is the app cant actually do lots of thing you want it to do so its essentially useless because you are just going to keep going back to harmony or the original IR remote. Why produce an app like that is it really that hard to make the app simply have a replica area of all the buttons on the remote? Before with my HTPC and denon I could turn the computer on or off or the receiver and always have audio working. But with the pioneer it kills the audio , the computer must turn on after the receiver. This sucks because every time we want to watch something or do something we gotta close all the windows and restart, (happens with AMD or NVidia) . Also for whatever horrible reason they didn't include a 12v trigger out on this thing and I can never seem to set a smart switch to the right sensitivity to reliably control my amp. The whole room correction also was not particularly successful for me, it kept telling me my speakers had the wrong polarity no matter which way I switched them, sometimes I would not change anything, run it again and it would tell me different speakers were wrong. lol?
If I were you I would just jump ship and look at someone else like denon.
