Thanks, here are the conclusions by oversampling from Dan Lavry:
Theoretical sampling retain all signal information. Practical considerations take advantage of higher then theoretical
sampling rates. Most analog to digital converters take advantage of higher sampling rates to overcome undesirable high
frequency rolloff problems. Oversampling simplifies anti alaising filtering requirements and provides room for phase linear
transfers. Storage and processing economy requires conversion from higher to lower sampling rates (downsampling). Data
found in compact disk recording and similar formats is often oversampled prior to digital to analog conversion, to simplify
anti imaging filtering.

I dont know, but f.e. it is not only me, but some other listeners said it too. We listened to some songs streamed via Tidal, originally recorded at 44.1 KHz and oversampled to 192Khz or 384Khz and there was really noticable difference. We heard more details at 384Khz compared to 192Khz. We have tested it again and again with the same result. That was the reason why I wanted to test it in Synchron Player this way and I did not understand why I could not get it work with 384Khz. I wanted to compare it (192 vs 384), if I would hear any difference like I did with Tidal. Hmmm..
