My experience is that remasters sound worse. I think newer A/D is probably far superior. But even when they don't try to increase the loudness, I think they sound worse. The highly acclaimed, latest remaster of the self titled Dire Straits from Japan is lacking some of the voice and instrumental timber of the original CD release that I listen to on Tidal. My theory is that the 40 year old master tapes have degraded, so you'll never be able to make a better release.
Is remastered mainly just less jitter?
When a CD is remastered is it simply just less jitter???
