I just got my ultrasone 900's yesterday and I listen to some of the same music as you, my favorite genre being "Liquid Funk", I would call it Melodic Liquid Dnb myself but that's besides the point. Most of the music I generally lean towards is the melodic driven stuff, often with piano, horns, soaring vocals, and driving synths. Thus far I have found these cans to be kind of disappointing in how shallow the mids are. Granted they are new, so perhaps some burn in will help open them up, I also need to try amping them and playing around with the EQ a bit, but as far as first impressions go.... Well, I've got my fingers crossed that the mids get found alive.
Everything else sounds amazing, the bass is well structured and the highs have a large stage to play in, and for that neurofunk you posted, I don't normally listen to dark stuff, but damn you're right, it sounded really good.
