I read through that twice. You have a CD with a performance taken from a 78. It's not necessarily worn out. A high hiss level can be somebody who tried to transfer a 78 with an LP needle. The LP needle is narrow and it sits on the bottom of the 78 groove. It's significantly noisier than actually usi...

OP uses MP3...that can be a very sensible choice. Or not. The goal matters a lot. Nobody will contest that most of the better compression technologies can't be heard while they're working—they produce essentially a perfect listening experience.
