Seems to me that the IEMs are the “hardest boss to please” in that any “warts” are most likely to show up there first (and to the greatest degree). My thought would be that (given apartment living) anything that works in your IEM output can most likely be solved in the other outputs using output EQ (and/or console EQ in the PA) and I find it by far the hardest to get things “right” in my IEMs. Ditto with using studio monitors — typically if it’s “right” there (and the monitors are, of course, accurate to begin with) it should translate 95% well elsewhere.
