I owned a GK stereo amp setup in the 80's for playing all that shimmering chorus laden Nu-Wave crap. I ended up stacking them in one place instead of spread on each side of the stage, it just wouldn't cut thru the mix that way.
*The fact of the matter is: It
NEVER comes across in a live/stage situation and having your sound in one location is by far more controllable for you and the sound tech. The only time it sounds cool is when you're playing by yourself in the garage with a delay pedal pretending you're Andy Summers.
