The problem with transimpedance RIAA is that you have to consider the output impedance of the stage before the frequency shaping network and also the input impedance of the following buffer. Both impedances appear in parallel to the frequency shaping networks.
Best is to publish your design and then one of my team puts that in the simulator.
I still use pencil and paper hard mathematics plus trimming but i know that i am a dinosaur.

A bit massive, sorry ...The Black Sun - The Alchemy and Art of Darkness
Not yet,Intravenous, i suppose.
still trying the oral way.
Btw,
this black sun stuff really seems way to tacky to me.
"Nabelschau", you know.
One last thing for tonight. This is what one of my teachers has to say :http://www.adamjhill.com/Hill + Hawksford - RS25.pdf
original Paradise boards
I hope this means first batch ?

Yes, these are rev1 boards. I tried all the tricks I am aware of to get rid of the oscillations, but these are pretty stubborn (stuff for me to learn, I guess ;-)
The rev2 boards do not have that oscillation issue, I think. I did put transistors with HFE=510 in mine and it works beautifully. Don't know what Le'Flu used exactly , but he also has rather high values for HFE. His boards also worked at first turn-on ;-)
I got my original Paradise boards from Hesener today. Many thanks. They still have an oscillation problem. Let´s see what i can do.
You are welcome! Please share your findings, this problem is really puzzling me....
Thanx Alfred,
ordered them last night.
I'm fiddling on a "Warenkorb" for the Paradise.
you have mail....
