Unsound, I have also outlined how anyone with modest test equipment can prove what I have said for themselves. There are even 'goners that have set up the test themselves and come up with the same conclusion. Check the archives; your statement to the contrary, I've not seen 'numerous requests'; please refrain from misleading statements.
Nelson and I are often on the same page. I often refer people to the distortion article on his website:
https://passlabs.com/articles/audio-distortion-and-feedback
In it we see that adding negative feedback does enhance odd-ordered harmonics, which *maybe* you could sort out by having even more feedback, although you would need to add more gain to do that, likely requiring even more feedback...
The fact that feedback does have this effect of increasing odd orders was also documented by Norman Crowhurst 50-some years ago. You can find his articles on http://www.tubebooks.org (vol. 3 of Basic Audio).
I totally concede I have a bias towards tubes, although if you were to check the archives I have often mentioned that I think we can get to the same performance with transistors, but they often fall short on account of its a lot easier to build a linear circuit with no feedback using tubes than it is with transistors. With regards to the other manufacturers, the debate has not actually occurred as most of the ones you mention are not active on this or other forums that I frequent. However I would likely point to past work at the links I dropped above for starters.
As far as the human hearing rules, the fact that we use the odd orders to determine how loud a sound is is easily proven with modest test equipment. I'm happy to provide the test procedure if you like; Unsound that goes for you too.
How do you debate with equally renowned SS builders i.e. Pass,Gryphon,Vitus,Boulder.Soulution etc. who would I`m sure insist their products produce music as'real' as any tube component and possibly better?
