You'll have to test and experiment a bit...

thanks a lot for your comment. It's not about having the pretention to make it "better" ... just having the J-fets and enough to match them...

Would you have a guestimation of what Idss to aim for ?

Idss is dictated by Pd_max but it's not crucial, non-linearities are too high, as well as Zout.
I would not do it with that part, but if you insist, go for it...
Please don't use private messages for question related to audio projects. It defeats the purpose of the forum.
