I think the idea of very near field listening to ascertain what your room is doing is a good one. You might buy Jim Smith's book Get Better Sound, which has all kinds of ideas about set up that don't cost money. Positioning in the room is pretty critical.
For me (not a drummer, a keyboard player), much has to do with the source material. Those jazz recordings that often sound great are typically less cluttered and more simply recorded.
I think there's a temptation to 'buy more gear, wire, etc.' as a solution in the never ending quest. I'd start with the room, and positioning (not treatment as such, which you can get to later to the extent needed).
