I haven't listened to Ohms since I worked at an audio store in the mid-'70s, but I have owned the OMD-28's little brother, the OMD-15, for 1-1/2 years, and the concerns leveled about the OMD-28s have no substance. These things are seamless, both in dispersion pattern and crossover points.
As for placement, the Mirages are very forgiving particularly in one way--you will always get a room-filling sound with realistic timbres regardless of where you place them. They are not naturally bright, though you can control brightness by opening or closing window shades and deciding on your wall hangings.
There are two placement issues with the OMDs, however. If you want that deep, holographic soundstage, you want to pull them further into the room and place them wider if you can. If you put them where you put a typical forward-firing speaker you'll get some center clustering, though the timbres will be spot-on. If you want a sonic hologram, bring'em out into the room.
Secondly, the OMD-28s have very strong bass down into the 20s, so that's another reason to have them out from the front wall. I have my OMD-15s a little more than 3 ft into the room. If you have the room to bring OMD-28s 4-6ft into the room they'll probably blow your mind.
The other thing to consider is that these are fairly easy to drive, reasonably sensitive, but can absorb huge amounts of power and translate that into dynamic range. Even my little OMD-15s are bi-ampable and rated for 250 watts power handling.
I have had live music in my living room, and no speaker I've had energizes the room and reproduces the correct timbres as precisely as the OMDs.
