Shannon-Hartley Channel Capacity Theorem and textbook Psychoacoustics, Acoustics for real world room noise floors suggest we're no too far off with Redbook CD Audio
 
as well as the 3 decades of people outraged by Digital Audio not coming up with more than a handful of somewhat Scientifically Controlled listening studies "proving" 16/44 inadequate - and those few not replicated, haven't made it into the Psychoacoustic textbooks yet
 
 
Shannon-Hartley Channel Capacity Theorem is the Engineering Definition that best allows comparison of analog vs digital "channels" like recording/playback chains https://en.wikipedia.org/wiki/Shannon%E2%80%93Hartley_theorem
 
Stuart's whitepaper is pretty good for showing human limits and digital audio formats, go to the graphs at the end, scan back for the associated text: https://www.meridian-audio.com/meridian-uploads/ara/coding2.pdf
 
 
and Psychoacoustic testing by now has long experience, has evolved some standards: http://www.delta.dk/imported/senselab/AES125_Tutorial_T4_Perceptual_Audio_Evaluation_Tutorial.pdf

It will be interesting to see the results. Hopefully you can understand some of the skepticism on here: people haven't been able to reliably show the ability to discern improvements from hi-res, and that's even with hi-res content actually in the track. It's thus hard to accept that people would be able to discern improvement from upsampled Redbook, unless something like an audible filter, extra distortion, boutique dither, or switching issue is the cause.

 
I have not heared differences when listening to the high resolution version of a said track, Linkin park for example has high resolution, I know the songs very well, and did not hear any differences with the high resolution versions. 
 
I accept the fact that some might welcome my ideea with skepticism, we will see after some time how this will evolve.

The degree in question I think might be a PhD in being delusional. Confusing a clear challenge as a plain liar and bull diseminator, plus a request to show actual evidence of claimed PhD student status, with "welcoming an idea with skepticism." Oh boy...
 
I will refrain from too much hostility not only after the suggestion, but because I see it's pointless. Guys, I suggest simply behold the red flags accumulating, and avoid wasting your time with this "PhD student."
