I tried those and some SRH-1840 pads and they make the bass totally go out the window on the DJ100. With the DJ100 it depends a lot on a good seal and the size of your ears.
The DJ100 can probably sound muffled with stock pads for those that have huge ears. SRH-840 pads do work well for some with the DJ100 but not for me.
Too much air between your ears and the driver and there is too much treble presence and you get a thinner sound. I think this is why the SRH-840 pads were so bad.
Surprised that I didn't get lots of noise/hiss with the DJ100 and Vali. It was pretty silent and it's 38ohm.
Vali was pretty amazing with the Q701 and wish I got similar results with everything!
BTW that driver in your avatar looks very similar to the DJ100 driver:
(it's not a KSC75/PortaPro driver)
It's actually the Fidelio X1 driver, maybe that driver design is what guarantees a great headphone.
