Let's see some documentation rather than a bunch of miscellaneous youtube videos....
I just posted a link to a bunch of articles, open it up.
The CEO of Harmon listed one of his top priorities for Sound United was to get a handle on the quality of their supply chains.
I had two premature failures in a row, and I don't believe that was coincidence.
I still have not got my 7706 back, but I have been told they have sent it on to a different service center in Kansas. That was the one where i spoke to avery nice service tech about repair of my 7705. He told me they were having an excess of board failures and were out of a lot of spare parts. He thought the issue was suspect components.
Anyhow he advised recycling of my only five year old 7705. I did, which I regard as a disgrace and major black mark against Sound United.
The OP is asking for advice about a new AVR. My advice is to avoid anything made in Vietnam like the plague.
Now Trump has imposed a 100% tariff on China again. So that puts Chinese products right out of consideration.
At the current time I advise purchase of units made only in Japan, Europe or US.
It was liberal policies that made US manufacture uneconomic and now we are paying a huge price.
Fortunately almost all the equipment I own says, made in England, Switzerland, Japan and USA. Practically none comes from anywhere else, and I have lot of gear from the seventies and even sixties working just fine. And that is the way it should be. The short life of gear these last years is a massive disgrace, and contributing to low sales of systems and forcing of disposable soundbars. Also we have a proliferation of the wrong equipment, with multi channel equipment proliferating when most rooms are unsuitable for it. We need good two channel gear and that should be cheaper and more reasonably priced than thrown together multichannel gear of highly suspect provenance. Things are really of the rails at present, and yes, way off.
