Isn't the filter we use in our playback preamp a reverse RIAA circuit and the one used to cut a record a RIAA filter?
The RIAA filter reduces the bass and boosts the highs and then we reverse that process when we play the record back.
I think it would be better to call the cutting RIAA filter a pre-emphasis filter and the playback filter in our preamps a de-emphasis filter.
That would make the "Lipshitz reverse RIAA circuit" a "Lipshitz pre-emphasis RIAA circuit".
