Which would you guys say comes out on top for gaming and music? Which has the superior soundstage and bass response?

I'd say from memory probably the dt990 has more bass and trebble, really weak mids though, I mean, the first thing I tought when I put them on was: wow, huge soundstage, fun bass (although not a fun of the smile equialisation) and what a terrible fake plastic voice haha.
The ma900 on the other side, are all about middlerange, sometimes trebbles are a little to faded. I'd say they have enough bass, although sometimes I get the impresion that they could go deeper.
