40 dB SINAD is certainly audible.
I think I am reading that the problem exists for a 4700H used in a 2-channel setup.
I don't know why that would be considered unusual, especially by the myriad of posters insisting that feature and power requirements are totally satisfied by an AVR.
They are the most economical and (usually) reliable choice.

That's only if one use it in a not very common condition. There is no issue for the following conditions that I think the majority do for two channel listening.
a) Use analog inputs.
b) Use optical or coax inputs.
c) Use HDMI but leave the speaker configuration alone.
On c), I have never touched the speaker configuration once auto setup is done. So my 7.1.4 speakers are always on. If I play the 2 channel track on a SACD, BR or whatever, and select stereo, direct, or pure direct mode, I will be listening to 2 channel playback even though all the other speakers are still configured.
Why would you or any one do what Amir did in his test? I would think even him would not do such a thing, and he did it only because that was an available way to run his test using his PC as a source? What did I miss? Just very curious about why you seem to think this imperfection is a big deal for practical applications, or you are saying it needs to be fixed because it is repeatable. If so, I agree.
If I read him right, I think Amir himself does not think it is problem for us users, not bench testers.
