> Not entirely silly. Yes, the purported benefits of this high-fidelity audio are imaginary or even include undesirable traits. However, when most "remasters" of pop music today involve the dynamics being boosted to "loudness wars" standards for a target audience of people listening to the music through earbuds in the street, the 24/192 downloads or SACD releases are often the only way to hear the album with real dyn…
This. Once the "master" is treated with the maximizing limiters that are used in the loudness war the files are just rendered into their separate file formats. If the SA cd promised that they reloaded the source tape/protools/whatever DAW was used and remixed/ remastered the songs to actually have dynamic range then I would be interested. As far as I am aware this isn't happening, and is implausible for any record of…
Many SACD reissues do go back to the source tape. This is a frequent cause of complaint with SACD reissues of classic jazz recordings from the 1960s: sometimes you get better sound in terms of dynamic range than any previous CD issue of that recording, but in the meantime the source tape may have deteriorated in parts.
Even with recordings from the “loudness wars”, there is sometimes room for dynamic range improvement when remastering. A good example is Rush’s album Vapor Trails. This was an infamously botched recording upon its original release, on a scale with Death Magnetic. Because loudness-wars treatment plagued the original tracks before mixing, the damage could never entirely be repaired. However, the additional process of compression applied to the source during transfer to CD could be reversed, so the album was eventually reissued as Vapor Trails Remixed, and while still flawed, that reissue has a lot more room to breathe than the original CD release.
