You raise a good point, Swede and Blue Bear, which I learned the hard way: monitor choice is as subjective as it gets. When I recently bought some monitors, I couldn't get over how much I (sometimes) liked the sound of monitors that I'd seen trashed in forums--and how I disliked others that I'd read raves about. Maybe it was because of my studio's strange acoustics, maybe it was my ears, maybe my musical preferences--but I realized how
*personal* my tastes are (even for so-called "flat" response).
All I can add is that some monitors add controls for fine tuning the monitors' EQ response, which I've found to be wonderful in my own home studio. This tuning is subtle, but just effective enough to adapt the sound to your own acoustic space. I ended up buying monitors that allowed me to make such subtle changes, and I've been very happy with them. I'd suggest checking any you buy to see whether such tuning is possible.
Good luck,
J.
