I've owned the original CD reissues of Pink Floyd albums from the 70s and 80s and very familiar with them. As a Qobuz subscriber, I just listened to the new high def versions and did some time synced fast switching direct A/B comparison. To my surprise, they did NOT squash or dynamically compress them! The dynamic range sounds and measures the same as the old CDs. The overall voicing, tonal balance and sound is almost the same but there are subtle differences. Some albums like Animals always had a bit of midrange cast to them, which they smoothed on the high def version making it sound just a bit better. Of course, that is probably due to remixing & remastering, not due to the 192-24 bit rate. The Final Cut has a new track, previously not released apparently because they didn't think it was good enough to be on the album, and I agree. My CD of DSOTM was the MoFi, and it sounded the most different of all these albums. The speeds didn't match, as the music drifted out of time sync even when the digital playback counters were perfectly in sync. So apparently one of the tape decks wasn't properly calibrated? Which one, who knows? Also the MoFi had a touch more deep bass extension, but less HF extension and a bit of midrange emphasis, so the new high def version was better in the mids & highs if a bit weaker in the low bass. The alarm clocks on "time" sound better, one the few areas where I didn't have to squint to hear differences. I do not think these are resampled versions of the CDs because (A) they sound slightly different, (B) the playback speed is slightly different from the CD versions, which suggests they replayed the analog tapes, and (C) they have slightly extended high frequency response to around 25-30 kHz in some places which the CD could never have.
Overall, Pink Floyd's albums were always very well engineered and the originals are some of the best sounding rock albums. The sonic differences generally are an improvement, but very slight, almost identical to the originals. I've been disappointed with most high-def reissues that sound worse than the originals, but these are the exception. If you already own the originals, they're not worth buying again. But if you don't already own them and you want them, I'd say these are the ones to get.
