Looks like things are progressing towards a hopefully satisfying resolution for both myself and Onkyo.
Jose just sent a Service History Request to my Service Center, requesting such records as he is looking to exchange my unit.
I'm not sure if he is planning on exchanging my unit with another NR-809, that I won't agree to, or if he is going to offer some sort of Onkyo Dollars towards purchase of a upgraded AVR, or an even swap for a newer, comparable model?
This is good for Onkyo as it keeps me as a happy, potentially repeat customer who speaks good of the company on Social Media and Tech forums and to friends and family who seek purchase advice.
Its good for me as I'll no longer have the burning rage and anxiety inside my head every time I go to turn on the NR-809 expecting it to fail. On numerous occasions when hauling down into the man cave/AV workshop and back up stairs to the family room I've had urges to just smash it down the stairs and walk away from it and its hassles, glad I didn't.
It remains to be seen exactly what Onkyo will do, but I must say Jose is an asset to that company.
