THANK YOU, to all, who have extended a supportive ear, helping us grieve over the loss of our Onkyo, under such scary circumstances. It's been therapeutic for us to be able to vent here and receive some needed validation. We are now ready to put our hard-feelings aside, because we've decided that such emotional toxicity is not good to carry into the NY.
We will purchase another receiver (not Onkyo!) and if we are able to have success with Onkyo replacing our burned-up unit, we will either sell it, or make it a gift for someone, along with a little fan

, and, generous warnings.
We will definitely follow-up with this thread when, and if, we are able to make Onkyo assume responsibility for their product, or when we get a verdict from Amazon's legal team.
We're currently considering the Pioneer VSX 23THX, or the Yamaha RX-V 3800 BL, but the more we look, the more confused we become. We'll peruse the other threads here and see what folks have to say about these units.
Thanks again
