I've been reading about how LPCM, DSD and red book audio work a lot the last few months. I find it really fascinating how the analogue signal is rebuilt from the digital samples. Very cool stuff.
Not to mention when the cd player came out, there was no other technology around in the home that could process 750MB of data so quickly. Think about microcomputers in 1981. It really was from the future at the time. The main reason I ditched it was, I didn't want to upgrade to another cd player in 2019, just seemed counter intuitive. They are just literally digital and whether it's a flac file or spinning optical disc (not servicing that in ten years and want as little moving parts in my system please).
