Yeah the Onkyo SHOULD last longer than that. It just seems there is a lot more doom and gloom about possible HDMI issues, etc.
The funny thing is its hard to tell exactly if the 809 is actually prone to the same issues as previous models. Its clear the x08 and earlier had problems, but not quite as clear about the x09 and x17/18 models.
The 809 is "old" at this point, but really need to see what happens after they are 3 or 4 years old. Some of the earlier models lasted that long too before they died so it remains to be seen if the x09 lasts the same, longer, or shorter.
Im very surprised Pioneer doesn't improve the OSD, but it seems like the higher end Elite models might have a slightly better one than the lower Elite/1222-K. I guess they want to reserve it to spend extra $$$, but having two different OSDs doesnt make sense to me, seems like it would cost them more to have it that way than to just give every model the same one.
As far as apps go, Im not sure if I can develop one for the Onkyo. They have their own Android and iOS apps, so they did it somehow, just not sure how "open" the API is. From what I hear about the Pioneer app, Im not sure you would even need to write another one....every review Ive seen about it said its that good.
And as much as I like Audyssey I think I would actually like MCACC more. Might take a bit to get used to and "tweaked" just right, but it seems more powerful.
