Some have, but for sure not all. In another thread, to be unnamed, you've wrote (to paraphrase) that a configuration error could be a cause of the "optimistic" claims of the Marantz AV 10. Me? The dude got a new toy and won't admit to any misconfiguration, and his previous AVP are now classified as "junk" after extolling their virtue for years as not AVR.
I did not mis configure anything. I set them all up correctly. I never had a major problem with my AVPs until the 7705 and 7706. I firmly believe the reasons, are suspect components by counterfeit components, and interior layout. These last units were basically AVRs without amps. The Atmos versions do create a little more heat, although case temperatures did not go over 95F. But from videos I have watched of disassembly on YouTube, the interior design is not good. with circuits one above the other and hard to get to. From the behaviour of the failures, I have a strong suspicion that some components were overheating due to bad interior design. So now I have made sure that I have a unit that has nothing in common with an AVR. It also seems that in order to get a spacious layout these Atmos units have to be large. This AV 10 is way bigger then any receiver I have ever seen. And yes, it does sound better. Only time will tell if it proves reliable over time, but I every expectation of a long life.
Two units that had background you can hear in a quiet room with failure at 5 years and one at three months. I have no hesitation in giving a junk classifications to these units. So I can in no way recommend them. That is based on experience.
So, if an AVP that is the size of most receivers has premature failure, then I would imagine adding a bunch of power amps will only add to the misery.
Yes, at the moment I am very happy with my AV 10, which is by far the best AVP I have owned. Only time will tell if it has long legs.
Now I am going to start a thread on AV and the barriers of interior design.
