DJM-750 mk2 - bass way to fat, heavy, punchy

Hey guys

First time posting here.

I own a DJM-750 mk2. I use it with two XDJ-1000 mk2.

All three devices are connected to my pc(win 10) via USB. For recording I already tried Rekordbox 5 and Traktor Pro 3.0 (always using the newest version and the newest firmware).

So, my issue here is the following. When I listen to my recorded sets (recorded with Rekordbox 5 or Traktor 3.0, doesn't matter witch, they have the same problem) the bass is way to punchy...too heavy..too fat...hard to decribe. It doesn't sound as the original wav at all. This can be a cool effect when playing something more tech and progressive. But for some genres it's really annoying. And it destroys some songs completely. I simply can't figure out how to turn this fatiness off. I assume it comes from the DJM-750mk2.

Any help is much appreciated!
