Hello all,I search advice on these, as to know which models are good for audio projects for currents sources and sinks, apart from the ubiquitous DN2540. Looking for both N-channel and P-channel varieties, with Vmax > 200V, various currents. Any suggestions appreciated (Part numbers).

below 1mA, 500V - Supertex LND150
100mA, 450V - IXYS IXCP10M45S
up to 900V - IXYS IXCP10M90S
... but I prefer 100mA 1000V version IXTP01N100D.
Not cheap (mouser: 4.73USD), but IMHO it's the best (for me).
That part is being phased out, as far as I know. And the latest batch will not do the rated current like earlier ones.
Currently Kevin Carter at K&K Audio is using the IXSYS 8N100D2.
Too bad about the 1N100D. I use it on the bottom cascoded with a 8N100D2 on top. With the new batch Kevin could obtain a max of 40mA with this cascode combination and went to using the 8N100D2 for both devices. Fortunately for me I have a stash of the older product.
