On what basis are the numbers "a bit of fun"? Lol, you're going to have to back that up with some contradictory evidence. Are you saying that the Foobar plugin is somehow giving erroneous results.
Regarding mastering, are you suggesting that LPs are cut from the CD track? Incorrect.
The original studio 24bit master acts as the parent, then the post production team mix it for the medium it's going on. So CDs are typically pushed to 6dB or worse. Because of the limitations of the LP cutting process, the levels are backed off and you usually get 10dB minimum.
If you think LP masters are just the CD master played around with, you'd be dead wrong. You only need to look at the comparative waveforms from the same ripped LP and CD titles to see that.
And ironically a lot (but not all) of the 'hi-res' titles being championed are merely upsampled from the 16-bit recording, again as shown by the waveforms. HD Tracks were famously taken to task over this - a high proportion of their library contained them.
I have the Daft Punk album on vinyl. It sounds amazing. It's certainly superior to the CD version, but I haven't compared it to the
QoBuz hi-res option.
