Question which current for small FETs?


as written in a tread before I am planning to build & test the Pass D1 i/u output stage adapted to 0,1mA peak current of a TDA1547 and enriched by CCS´s. I created the attached schematics. The signal path is using 2SK389 as signal FET and 2SJ103 / 2SK246 for the CCSs.

Your experiance: which bias should be used, at which value does the 2SK389 sound best? In the schematic I have shown e.g. 1mA. But it could be much higher of cause.

Thanks for tips!
