Honestly I found it interesting to compare different sources myself. I just did trial memberships with different platforms and compared side by side. I did hear differences although I am not sure if just one is a tiny tiny bit louder than the other. Out of spotify, tidal, Qobuz and Amazon music I prefered Qobuz almost every single time blind testing, but it could be what I mentioned above. It sounded definitely different from Tidal even though it had the same Resolution / lossless files.
