It is certainly believable. But it shows that the person telling it doesn't understand the reasons behind the event. Which in turn raises doubts about their other claims. Look for "Clever Hans effect".

"Direct Energy" seems to be a marketing term. Feature discussed here is an optimization of amplifier power losses. There is no mention about it in manual, and there is no way to turn it on/off. IMO this is a similar feature, that Denon calls "Eco Auto". See Denon description of "Auto"...

It is not an issue, it is a feature.

Is it a new discovery? I don't see any indication of this problem in distortion measurements by Amir.

Yamaha, Denon and Marantz AVR offer loudness control. This is done properly, based on acoustic measurements of playback sound level. It works quite nice, unless input source level is realy wrong.

I use the same curves for all speakers, including subwoofer. I assume they work the same in the room, regardless of sound material they get form a multichannel track. I had Audyssey for a short time. The extra tuning of Dynamic EQ was that it increased volume of rear channels. Maybe maybe there...

Sound, that we perceive, is a periodic waveform. Distortion, that we talk about in audio, is a periodic waveform too. To reproduce single period of 1kHz on CD, we need 44 samples, which would be 352bites at 8bit sampling. 44 of these bits are imprecise, but with dithering they are converted to...

If you used 3 posts.

You could post like that: See, 3.1 quote ;)

Sure. We talk about AVR post processing and home equipment configuration. Format nomenclature is not the topic of the thread.

If it adds up, then 4 cats.

Denon uses to describe their x3800 as "9.4 channels", so it is correct :)

What about 13.1? Are users of Auro 3D technically incorrect, when describing their system?

Looks like it is designed for audio. 6dB between peak and average power should be good enough. Probably amplifier modules get similar specification.

Sometimes a trafo simply hums. It could be production defect or trafo could be designed for lower voltage or higher frequency than actually used. In the later case one can try auto-transformer to reduce supply voltage. You can try to deal with the problem, but IMHO the hum you hear is well...
