Summary: When I first bought this receiver I was thrilled about all of it's capabilities and features. The auto programing, number of HDMI inputs/outputs, and airplay are pretty awesome. The one thing that I did not read though during my research was the fact that the HDMI board is extremely unstable and crashes quite often. It all started roughly one year after I purchased it from Amazon.
Summary: Folks, One would expect that upon arrival it would be possible to safely plug in the VSX 1121k7.1 receiver. Like two other contributors to these reviews I have found that the plug does not fit. The plug is of Chinese manufacture and it is obvious that Pioneer has opted to save a few dollars (yuan?)rather than insure tight tolerances. I am returning my receiver for replacement in the hope that the tolerances are so poor that I may, by luck, receive one that does fit.
