Great
I remember you spoke of replacing the pot. 2/3 down on this page maxkur shows a new one (RK097), and I think the following posts describe that the direction changes, but not sure if something is lost in translation.
I've changed all caps in both of mine now, 4 x nichicon kz in the second one, and output resistors gone in that one too. I can't find any negative effect from removing the resistors completely when used with 32ohm buds, but I don't know what to listen for. If the risk is that the bass is rolled off it seems not; I've played some testtones and with emx500 I get 20Hz quite clearly and at the same level on both z1's. And nothing gets warm inside.
Edit: sorry did'nt realize I have 220uF at the output of the one with no resistors
I've got a 10K Log taper pot to go in the Z1 - but the main mod will be to swap the circuit etches going to the pot, so that Clockwise Rotation = Volume UP.
If I swap capacitors, I'm going to stick with values that are small enough that the case can still be closed.
