If it was not clear distortion or similar noise you heard early on, its possible that the speakers just sounded better after a while because your ears adjusted to the different sound.
I'd like to see a picture of your entire listening room, but I'm suspecting that you might just have tight quarters that might call for a smaller box in order to breathe and sound open and free. That is a good thing perhaps because in general a smaller speaker should cost less to get right than a larger one.
A lot of people fear omnis and their room interactions, but with my pseudo-omni Ohms, I'm finding these are actually less sensitive to room acoustics and easier to place for good sound than other box and planar designs I've used. So I think omnis, again if not too large, are not a bad thing to be considering, but a smaller conventional box speaker design might be able to fit the bill as well.
