Yes, this is basically the case with an nth-order low-pass filter. And the internal resistance of the source is simply a coil with X = Omega * L.
I have settled on 100k , 100pf extra capacitance for AT VM95ML frequency response is spot on now.
Okay,
so that would be your load case:
Rp<100kOhm and Cp>100pf.
But have you also measured something, for example the complex, resulting input impedance of your phono equalizer? I can assume that you are not talking about OREAD.
