hmmm that is what happens when you simulate deep in the circuit, you have to set the caps high, or completely remove them, Will set them back to right value later today....but where it say 1 its supposed to be 10mF

There is still a small improvement to be made. R17/R29 can be split in two (2 x 220) and from the center a capacitor could be connected to ground (470/1000uF). I know the power supply is very good, and this is not ‘needed’, but still…

Will add that...and post new schematic later toady.... to be clear I suppose you mean R27 and R 29.. True that takes even more noise out, and reduces the resistor current noise at the same time.. good thinking..! (again)

The C-3-4-8-9 is supposed to be 10mF and 3.3 Uf for decoupling, though the decoupling is not needed on a high impedance current mirror, I can still hear it, and if at Mundorf tinfoil cap is used it add's a pleasant calm warmth to the sound. ( just one of those things you can hear, but not explain)
