So, if I understood correctly everything that was written in this thread is the following video is not some voodoo magic? :) (the interesting part starts at about 0:50sec):

Maybe because it's creating an illusion, that if you payed for something and all the important audio reviewers are saying that something sounds better that something else then it really sounds better, even if you don't hear any difference. But you don't want to be worse than others so you buy...

Well. Cables sure matter as the electrical conductor. But if people are claiming that "this or that cable sounds amazing" why do they even bother to connect speakers or headphones to them? ;)

A propos HRTF. Sony's doing some crazy measurments for its next gen console. - https://arstechnica.com/gaming/2020/03/sony-promises-ps5-will-load-content-100x-faster-than-ps4/

And what if 1000 people think it's not louder or too loud?

Yes, this upgrade was a painfull one. I'm glad I help you a bit :-)

Same here. I use Hiby R6 daily but I bought Apple's lightning to jack adapter to see if I'm going to hear any differences. I heard none and it was such a pleasent surprise. The only thing that changed was that I had to set much higher volume on XR that on R6 but I was expecting that. I'm back...

You are on Windows 10 so try this - skip step 1. Do not install Qualcomm driver (if you already install it, please uninstall it and restart computer just to make sure). Start with step 2. Connect R6 to computer, wait to see charging screen and then press "Power", "Volume +" and "Volume -"...

That's perfectly normal :)

I don't think that Tidal allows MQA on the mobile app. At least MQA was not available when I was using Tidal on R6, but it was a while ago so maybe they changed their minds about it.

I was using W30 (not exactly W50, I know) with R6 and I liked the sound. For me it was the same as with FiiO X5 III so you should be good with both R3 or R6. Soundwise I can't compare R6 to R3 but for me both should sound the same ;)

I don't know, I like this new icon. I also like the changes to the interface. Looks a bit cleaner this way. It's a pity to hear about problems after the update, though.

One of my friends thinks that there are harmonics that are not audible, but they make you feel that music indeed sounds better and he is dead serious about it. Apparently it only happens on high-end equipment. Or very expensive, I'm not sure ;)

Yes, that could be it: Above quotes are from this article, but since I'm not a mastering engineer I do not know how true is it (although it was interesting to read) :)
