for biasing gain stages such as this I've found no better way than Schottky diodes, SiC providing greater voltage drop. They sound better than anything I've tried, particularly for phono applications and I've spent serious time evaluating the options. Although I've not tried every other diode possible Schottky diodes generally sound way better than silicon diodes to my ears.
Since they have very little dynamic resistance local nfb is minimal so they don't have to be bypassed. Therefore OP impedance is almost as good as running a piece of wire in the cathode circuit.
Serious resistors you are using btw, very impressive looking!
