Soundstage

I have a decent size room 20’x33’x9’.  Due to the placement of some large columns I need to place my equipment on the long wall.  While I can achieve an equilateral triangle between seat and speakers (11’ on all sides) .... I am unable to have the front of the speakers more than 3’ from the front wall.  I am using Avantgarde Uno speakers with Pass Labs XA 60.8 amp and AR Ref 6 pre.  Sources are Lumin X1 and SME 20.  The overall sound and imaging are wonderful.  There are two problems that I can’t seem to get right.  First, the soundstage is rather narrow ... does extend beyond the speakers (have tried every off to on axis position).  Second, the image is detailed/precise but not deep ... it just sort of hangs on the wall 3’ behind the face of the speakers.  I believe that the problems are due the speakers not being far enough from the front wall but I can’t move them out more (due to the columns I mention).  Any suggestions on how I might fix these two problems?

Very cool speakers,
after years of trying the equilateral triangle at 8 feet 
and trying to extend the 8 feet feet listener to my rooms max of 8 ft 6 in
I tried something different .
My speakers manual suggested 8 feet apart and 8 to 10 feet from the listener , so what's the difference ?  
The angle from the listener to the speakers ,
from 60 degrees to 47.2 so if you haven't already maybe try
moving your speakers to 8 ft 10 in  apart with your 11 feet to the listener
you'll have an angle of 47.2 degrees .
Just a thought and maybe worth a try .
