I'm not saying anything is special about discs, cd or otherwise, but not everything is "bit perfect" in some systems, and means of playback differ and one can perceive one as better in differing degrees. I have an SACD transport (yes, I think SACD is the best digital I've heard, higher res than Redbook), a turntable, a phono preamp and a DAC that sounds better to me than a PC playing back files or a streamer in my system and I don't use those as a result.
Enjoy what you enjoy! If they sounded better to me and I didn't have to buy more equipment to make them sound better I'd invest more time and money. But I'm not going to.
