It seems like higher-end Onkyo models are fine, but the lower-end models may be a headache.
I have a friend who does custom installations. Few months ago, a client insisted on a lower end Onkyo model like NR609. 1st one died upon arrival. 2nd one died shortly after install. 3rd one caught on fire or something.
Finally I think the client gave up & tried Pioneer. Happy ending.
I think the higher end Onkyo like NR800s will be fine. Otherwise, I would go for Denon/Marantz, Pioneer, Yamaha. Anthem.
