This is a really good article by Erno Borbely, a well known and very good designer.
Check the FET matching (Figure 5) & the quad JFET (Figure 8). I'm currently experiementing with that circuit :wink:

He is also selling those really hard to get JFETs and other high quality audio transistors at very reasonable prices. For 50% more he'll do matching:

And his kits (10% off this month!):

There's a very interesting mic preamp too! Haven't tried it, but I have build several of his projetcs in the past. Very high quality :thumb:
Some cool articles (tubes too ):

Nelson Pass is another wellknown FET enthusiast:

His Bride of Zen could perhaps be used in the Forssell Opto Comp:

Maybe Fred Forssell has something to ad being a FET fan too :grin:
