tried some digitizing sw - "plot digitizer" on sourceforge
I suppose the main lesson of AI is how hard it is to make a computer do things that are obvious and trivial for humans but it seems like these programs could be a little more automated - lots of hand trimming of the points was required
mathcad for display:
jfet solid lines, low noise cmos dashed
Input Voltage Noise vs Frequency from manufacturer's data sheets
no warranty of correctness expressed or implied but it still looks like the ad743 is the one to beat - thank Scott Wurcer

Mr. Ruschkowski brought this opamp (AD743, AD745) to my attention. Later I also discovered that Walt Jung recoemmend it as RIAA amp in his book "Opamp applications". Maybe I'll test AD745, it looks interesting.
