The article also explains how, on the other hand, many hi-res recordings are manipulated such that editing by the original producer as well as later digital transformations from one resolution to another wind up degrading the original sound quality.
This was a known issue all the way back to the introduction of the SACD format. It’s not necessarily degradation, per se, but definitely had strong evidence that the SACD versions were being significantly altered and remastered, perhaps deliberately attempting to convince listeners of the SACD superiority. It was an altogether different product than the CD version.
In modern times however DAC’s got especially good at playing even Redbook 44/16 format (CD) files, while pre 2000 DAC’s showed a large gap in performance between 44/16 and higher resolution formats.
These days there’s no difference I can’ hear that I can’t attribute directly to the anti-aliasing filter performance. CD’s sound a lot better and high resolution files sound just as good in PCM or DSD formats, so I prefer to save the storage space and stick to PCM.
