I know the benefits of using a CCS for the plate load of a gain stage, but is there any particular benefit of using a CCS in place of a resistor in the cathode of a cathode follower (either for a preamp or for headphone amplifier purposes)?
I ask because I just built a headphone amp with a simple LM317 biased at 50mA current draw in the cathode and 210V at the anode of the EL84 (configured as a triode), but find it clips very quickly into my Beyer T1 (a 600R load).
I can't get it to good listening volumes before clipping, and was wondering if I should just switch to a resistor.
Any help is appreciated!
EDIT: the title should read: "Does it make sense to use a CCS instead of a resistor in the cathode of a cathode follower?"
