It's pretty common where I live when someone passes that all their belongings are just moved to the curb for collection. I picked up one of these sometime around 2015 off the curb. I took it apart for parts. I was confused why a CD player seemed to be so over engineered and over built. I eventually searched up the model number and realized it was the first one to reach the US market around 1983.
I came across DCC (Digital Compact Cassettes) this month: https://en.wikipedia.org/wiki/Digital_Compact_Cassette. A digital cassette tape format with the players being backwards compatible with standard audio cassettes. Not massively surprising that I didn't remember them from the 90s, as they were about for roughly 4 years and lost to MiniDisc, which itself wasn't particularly successful. So many of the inventions of that era are a fascinating combination of mechanics and electronics.

Today everything seems to be a chip in a box and still it's often more expensive.
Am I correct in assuming this wouldn't be perceivable on a stereo, based on the speed of sound?
