I was still a kid when CDs came out. I recall some CDs, like Mercury Living Presence reissues having very noticeable tape hiss from the original master tapes that I could hear a lot easier than I can hear today on those same recordings. That might be a false memory. Or perhaps, I was going out of my way to listen for it because digital's big selling point was no tape hiss. Come to think of it, I know for sure that I had a Phillips classics CD (still have it) that I didn't realize for quite some time was actually from analog master tapes from the 1970s, so obviously I wasn't picking up on all the tape hiss. I only bought DDD back then, at the very start of the CD era, but somehow goofed up and bought that one, never noticing the difference. By the time I was buying Mercury reissues I wasn't the least concerned about it.
