You must be listening at a really high volume level (bad for your hearing) if you can max out the X3ii w/ 400i, I can't listen at more 95/120 which is about 87-93dB
You know things are rough when you are a loud listener and someone quotes a higher listening volume than you
Just curious, X3ii able to drive 250Ohm headphone?
I tried it with HE-400i, darn hard to drive haha, I max out the volume on my X3ii with high gain, though what I heard from the headphone is not with Low volume but can feel that it's struggling, not dynamic.
I would hold you a second there - not having enough power to drive aka not being driven well is a different thing than not enough volume. You're sure you didn't have EQ engaged at the moment?
