Right. Exactly. Could hardly have said it better myself.
About the only thing left unsaid is that yes indeed one could get a string of 1’s and 0’s from the output of a CD player. Just not the same one every time. And so no, the same sound cannot be replicated. Otherwise a CD would always sound the same. Which they don't. Because the CD is not digital.
Nurse! Thorazine! Man down! Costco hasn’t been paying attention. In the case of CDs the 1s and 0s are represented by transitions not by the ON or OFF. As I already explained it’s more complicated than you apparently think. The link I provided yesterday includes the allowable sets of data determined by both transitions AND the length of pits and lands.
Also, you are incorrect that - in the Case of CDs - the digital process is reliable. It is only *partially* reliable 🤭 within limits that are set by failure of the CD playback system to deal properly with scattered laser light and vibration, internal and external. Not to mention the obvious failure of Reed Solomon error codes and the laser servo feedback system to correct all errors. Wake up and smell the coffee! ☕️
Even CD players that are *isolated* have difficulty with laser reading the data on the disc because the *CD itself* is wobbling and fluttering. The CDs are often not perfectly round and the disc is often not absolutely level during play, which exacerbates this CD vibration problem. Yes, CD Compact Disc “works” well enough for those who don’t mind generic, thin, bass shy, brittle, honky, synthetic, congealed sound.
