With AVRs, it’s hard to consider one brand worse than the rest. In the last 10 years, I had two failed Onkyos, 2 Marantzs, one Harman Kardon and a Yamaha. I bought all of them second hand, and in all the cases, was picked up from someone who had never repaired them prior to it. While sending them for repair, I checked with the technicians if it was previously opened and they said no. I had a NAD which survived lot of torture and had no issues. But looking up online, the same NAD had Failed for lot of people.
Each one failed in a different way. In the same period I had lot atleast 25 integrated amps from all these brands (some real low end, some yesteryear hi ends) without any problems.
Right now I have a Denon x3300 which has an update pending. I have no plans in updating it even though the AirPlay doesn’t work for me right now

the front panel recently started acting up crazy, however via remote it works fine for now. After reading all the stories online, I decided to live with it until it completely fails.
