Yes i know they have been remasterd in 1993 jjs , but have'nt things have moved on since then ?
I recently got Dennis Wilson's "Pacific Ocean Blue" on CD and the sound quality on this newly remasterd CD is far superior to Paul's CD's .
Either I don't understand this, or you don't understand what's involved in "mastering". "Mastering" involves equalization, level matching (so that some songs don't sound louder than others), compression (to reduce the difference between loud and soft sounds), limiting (to avoid clipping i.e. saturation) and noise reduction (to reduce hum and hiss).
All audio that was originally intended for vinyl (or tape) must be remastered for CD, because the equalization and compression (among other things) is optimized and best suited for that particular media. For example, Vinyl can't handle a huge dynamic range, so music mastered for vinyl tends to be more heavily compressed than it would need to be for CD, which has a much larger dynamic range.
There are situations where the initial remastering for CD was quite poor. My first copy of "All Things Must Pass" was poorly remastered for CD. There was tons of hiss from the source tapes, and quite a lot of missing high frequencies. The songs sounded hissy and dull. Remastering of these poorly remastered albums was a necessity.
But Paul's remastered recordings were properly remastered, and short of simply "modifying" the sound with equalization or unintended harmonic enhancement, there's not much you can do to "improve" the sound. No, there isn't that much difference between now and 1993, as far as digital audio goes. Digital is digital.
"Remastering" in the context that most people are used to, is nothing more than the recording industry's way of separating idiots from their money. Especially when recordings are "remastered" that were originally recorded digitally and released on CD (DDD). This is a plain waste of money. Save yourself the hundreds of dollars you'd otherwise spend, and learn to use your graphic equalizer. The results will be pretty much the same.
Now... REMIXING is another thing entirely. I'd like to see all of Paul's (and the Beatles) recordings remixed and re-released. As far as the Beatles goes, If you have the Yellow Submarine re-release, those songs were reconstructed from the multitrack recordings and remixed for true stereo, while remaining as true as possible to the originals. I'd love it if all their albums were re-released this way (with the original versions too, for the purists).
I'd like to see Paul's 70's stuff remixed, bringing the drums and bass and guitars a little more forward in the mix, as well as being re-EQed and processed. Perhaps 5.1 or surround mixes?
