Yeah, that's true, they are digital, but still feel "old". I was quite amazed while playing a vinyl record, accidentally lowered the volume down to 0, and could still literally hear a bit of sound coming out, not from the speakers, from the needle touching the record. Then I remembered that it's the actual sound waves that are engraved in the record. Amazing stuff
I was blown away when I made a crystal radio and could hear (barely) the station with no power source but the radio signal itself! Digital broadcast makes this impossible, alas.
