Oh, I'd buy all sorts of tapes. But still, SSSSSSSSSSSSSSSSSSSSSSSSSSSS
and just the crispness of the sound was gone. I had a reel-to-reel which was indistinguishable from playing the record. But, RtR was just a nuisance. I finally replaced it with a MiniDisc player, which was just as good. Then recordable CDs, and then, finally, mp3.Interestingly, my old cassettes have not degraded over the decades at all, while the VHS tapes certainly did. |

There are a lot of reasons why you might hear the hiss in one system and not another... besides different tape types, there are systems like Dolby noise reduction. The noise reduction comes in different varieties and must be paired with the correct decoding circuitry... if the wrong type of noise reduction is selected at playback, it may sound noticeably worse. I'm sure you know this, but plenty of people on HN are too young.
Most compact cassettes used Dolby B. You could use newer systems like Dolby C or Dolby S instead, and it would get rid of most of the hiss. These weren't used much when cassettes were common because tapes made with Dolby C or S sounded horrible without decoding, and Dolby S also came out very late when cassettes were on the way out.
If you combine all of these things... a tape deck with a narrower head gap, with a high-quality CrO2 or metal tape, and Dolby S noise reduction, you will get something that sounds very good, like a CD.
This video has some samples with and without Dolby S, with type I and type II tapes: https://www.youtube.com/watch?v=nfgJFvHPLfc
If you were using compact cassettes for music production, like with a Tascam Portastudio, the situation was even better, since it ran the tapes at a higher speed.
