If possible , set the speakers the same distance apart as they are from you in your listening position . An equal lateral triangle , if you will . Then play with the toe-in
for best sound stage . Also put some sound absorption behind you . Keep the space between you and the speakers and the space between the speakers empty . If one or both of the speakers need to be close to a side wall or hard piece of furniture , put some absorption material there .
Put a mirror on that surface , behind the speaker face , and then go forward toward the front of the speaker . When you can see the face of the speaker in the mirror that will be the starting point for the absorption material . Go from there a foot or so further forward . You can use your absorption panel , a decorative blanket or tapestry or hang a heavy winter wool coat on a hook .
I've owned the JM Labs 1007's and did not get a lot of sound stage with them . On the other hand , I had the JM Labs 926's and received an enormous sound stage !
Good luck .
