Dear Perrew: Answering your first question and IMHO when you play a recording that was recorded with ( before ) a non RIAA eq. standard then you heard a totally different performance of what is in the recording that comes with a different equalization curve.
That's why some Phono stages comes with one or two eq. curves other than the RIAA standard, normally those recordings that are with a non RIAA standard were very old ones and that were recorded before the RIAA standard universal agreement.
Regards and enjoy the music.
