Ever wonder if they lost the master tape and rushed out the CD of that using an EQ compensated version of the album? I have.
This album was released in 1991 -- well past the CD's introduction. If it sounds like shit, it's because of the engineers, not the medium or the gear.
1988 -- also not an "early" CD.
Ditto. 1990.
Ignoring the unremastered stuff most of the things in your list were well past the "new" phase of CDs. If you'd pulled things from the very early 80's, sure, yes...digital was new. But in 1999 it was old, established, and well understood. If those albums sound bad it's not because of the medium.
Respectfully, there was a huge difference between the way CD's were mastered in say 1990 versus 1999.
The latest album I posted was 1991. Record something through mid 80's -1991 converters, then do the same with converters introduced from either 1999 or, for more amusement, from the last 5 to 10 years and you will notice a much better quality in the conversion and no tonality change with the later era converters.
Add to that fact in the late 80's and early 90's, people were still using Sony PCM-1610's and 1630's (glorified u-matic tape machines) that sounded like crap and introduced jitter IMHO. By mid to late 90's you had the last days of DAT and the beginning of affordable CD-R's being submitted for replication.
Also the Mitsubishi multi-track machine that was good in its time when it recorded "So" could be outperformed in conversion by most $100 USB boxes today. If I remember correctly, Now and Zen was also recorded on the same generation Mitsubishi machine.
It would not surprise me if Hold Your Fire was recorded on the same machine because it has the same odd EQ curve to it. Since they touted the album as being DDD, I doubt they would have re-EQ'd the master for vinyl or cassette replication to use for CD replication.
If you don't think that certain companies' converters contributed to some weird sounding CD's at the time, you never did a shoot out of gear with the same source being recorded. I remember even when the Tascam DA-88 came out and the Alesis ADAT came out, the studio I worked at recorded the same source of drums, guitar, & bass to both machines on loan to us, to try and make a decision which machines we were going to invest in, since we could not afford to own both formats. Upon playback, the Tascam had a very different EQ curve to the upper mids than the ADAT did. It was a different experience than using the converters of the last 10 to 15 years.
