Simply put, dumb s***.
Not the tweaking of eqs and comps is counting, it is the SOUND of the eqs and comps itself. Costed me a year to find out.
You can fiddle around with your eqs and comps forever, even have golden ears, if the gear does not have THAT official sound built in you better forget it from the start. I think no one can describe this sound, but you recognize it immediately if you hear it. And for sure HarBal or whatever does not have it.
