Just downloaded Tchaikovsky Symphonies at 24/96 with Yevgeny Mravinsky conducting the Leningrad Philharmonic Orchestra via Qobuz. I had an 320 MP3 of an older CD and expected better sound from the new files.
After 2 seconds it was clear that this remastering suffered from increased compression. The quiet parts have been lifted substantially destroying the tension Mravinsky builds. The whole thing sounds blown up and out of proportion.
The MP3 has a DR-value of 11, the 24/96 file DR9.
Stay away from the 24/96 version and make sure you find the old CD-transfer. Much better music.
