Dunno (we've been here before with this subject), I think Russell could have a point about 'hidden harmonics', although the mechanism for such is questionable.
As you know, with the Raspberry Pi/IQ Audio DAC, which is technically capable of reproducing high-res files, I have access to 10TB of music, on both my hard-drives, and amongst them are 1000s of high-res recordings, a number of which I also have the
identical album/music (same mastering) on standard red book. And I can switch back and forth between them, with a click of a mouse.
Unquestionably, to my ears, the finest examples of the high-res recordings that I have available, sound significantly better than their red book counterparts - and I can hear that (very clear) difference on a 50-year old pair of Tannoys...
