for me I found some static with a 100ohm resistor on R8 and jumpered R9 but with a 100ohm on R9 and a jumpered R8 I found dead silence on my 16 ohm awia earbuds. I *really* really must have messed something up while switching around because i don't remembering hearing hiss when I first tried a resistor with R8 but when I tried it again later on I still found some hiss with 100ohm resistor on R8 and a jumpered R9.
If you have dips you can just experiment with it yourself and find out which one you like better.
and also I found the volume much louder with both positions jumpered but it comes with hiss.

well lets say I left the volume knob untouched (with the amp off) I switched out the resistor for the jumper so that R9/R8 was jumpered and I turned the amp on and I found the volume to much louder than before.
I don't know why it sounds louder it just does...
edit: I'm not even sure if I can notice the volume difference with my HD-600's but I can sure notice the volume difference with my 16ohm awia earbuds.
