If ever there has been an audio advancement that lived up to the hype, including their forecast of the future of the technology, this is it. Here is an early report forty years ago. Sony did the software and since then no working CD player has ever played a note of music incorrectly. About 2/3 of the data on a Disc is devoted to error correction.

Worth saying now that the dust-up about the early discs sounding poor because the technology was flawed was complete BS. I purchased some early Nimbus CDs from the UK and they were perfect. It was the work of stubborn or lazy recording that took forever to simply do it right. There were no esoteric secrets or magic yet to be discovered. The technology was released fully capable, as recordings were being properly mastered for the the new recording technology in Japan and the UK before the complaints started.
