I have a reasonably large collection of RIPed CDs running on my NAS and served by Roon. As these albums have been re-released in HiRes, I often have gone out and purchased (mostly from HDTracks) the HiRes version. I’ve noted that it is frequently the case that the DR reported by Roon shows a higher DR figure on the original CD RiP (44/16) than the new HDTracks download (96/24 or 192/24). This is the opposite of what I would expect, I would think that the HiRes would have a higher DR figure. If it were very occasional, I would probably not have noticed it, however, it seems relatively common.
There are of course many variables – the master used, etc. I intended to hit the files with some other tools to further investigate the DR figures. I was wondering if others had similar observations.
