Dear @clio09 : I posted that very long post with all wider explanations from P.Ledermann him self 10 years ago and at the end of that post I said:
""" We have to read the whole history....""" and you did not when that post was " delivered " to you.
Here is again what Ledermann posted 10 years ago and that's is in my post:
""" Noise?? In fact, the RIAA EQ inherently reduces high frequency noise and distortion in "normal" preamp circuitry; making RIAA a Dolby of sorts. The absolute requirement for a fairly flat (EQ or not) preamp for the Strain gauge was a bit more problematic 35 years ago, as we had to create low noise circuitry for this "flat" preamp to avoid excessive noise compared with a standard RIAA preamp! Creating a circuit in this day and age with "ultra low noise and immeasurable distortion" is a joy, and very do-able. I would rather listen to this one gain stage and an ultra fast cartridge than anything else """
But you read it but not really read it. ! ! ! ? ? ? ? ?
Your last post makes no sense and is useless and does not makes any real contribution to this thread. I think you agree with this last statement.
