If you think MP3 offers superior sound, to either vinyl or CD, more power to you.
CDs are digital too.
Not a superior sound, but a high quality MP3, using a decent bit rate and encoded with a good encoder using high quality settings, is close enough to an uncompressed CD that most people, even with good equipment, couldn’t tell the difference. And a lot of the equipment that a lot of people listen to music on is not very good. The DACs built into most phones are crap, for one thing.
