If you have speakers next to side walls or rear walls in my experience it kills the imaging. One day, just for fun, pull them out into the room and see what happens ... you might find that the imaging is so wonderful that you can't put them back and you have to live with them in the middle of your room. Friends will laugh at you, but then that comes with being an "audiophile". You should see my listening room .. what a mess !
