a complete accurate VAS with JFET and BJT

[Stee]

to have an accurate signal
in voltage amplification
you need a minimum Load in each step
so JFET also until +/-25V is a perfect sensor
see my idea from Hiagra schematic

I am currently experimenting with something like this. The sound is absolutely fantastic.
Check also Borbelys FET line stage - it is almost the same thing

You need resistors in the sources of the second stage though.

Here is a working circuit:

Thanks a lot NriK

that is very intresting for me
Simplicity is the companion of beauty ...
so not like the cascode
do tou have a drawing of your best result?

I have not finished my experimenting, but until now it is very much like the second drawing in your first post, with 1k resistors in the sources of second stage.
