Yeah, I understand that - is the same for me with vague posts like “… and for some reasons his mixes come out with more stereo information” nothing to really grasp, nothing to compare, so not really possible to be more specific.
One thing I never understood though, is why someone who is doing a mix, and has all the single files and possibilities available for creating a stereo mix as wide or as narrpw as he wants, should need something like a stereo enhancer at the end.
