CDs remastered in the 1994 time frame can not sound nearly as good as CDs being digitally remastered today from the original tapes in 24-bit PCM technology. Any CD of older music was "remastered". That's how the music gets on to CD media. Your CCR Chronicle Vol 1 was first put on to CD in 1994 most likely using state of the art equipment at the time. Not 24-bit but probably 16 bit. Today, CDs are being digitally remastered to 24-bit technology and many do sound so much better than their original CD releases. There are a number of CCR CDs being sold as newly digitally remastered. I have CCR-Pendulum and it does sound a lot better than the original Pendulum CD I had purchased years ago in 16-bit. This was digitally remastered in 2008 and released by Concord Music Group.
Now taking this a step further, SACD Direct Stream Digital technology presents an entirely new way of reproducing music. With DSD SACD technology, you get something like 2,822,400 samples per second with frequency response extending out theoretically to 100,000hz (20,000hz with conventional CDs) and dynamic range achieving 120dB across the entire audible range (96dB with conventional). The result is superior audio performance. As Hifigy states, you can now purchase CCR in SACD format from Acoustic Sounds. I plan to start replacing my older CCR CDs with these over time.
SACDs are particularly important for older recordings and albums. Those need it the most such as CCR, etc. Hope this helps.
