Williewonka, my speakers are 9 feet from the back wall so there is plenty of depth but the imaging was a bit diffuse. This sharpened up nicely with the addition of extra clock between my server and Dac so it can be assumed that phase and timing are a contributer .
Depending on the speaker , I've heard improved depth by positioning the speakers closer together with no toe in but you probably tried this.
The addition of a pair of well dialled in subs can also be beneficial towards your goal. Not trying to tell you how to suck eggs but perhaps you answer is a combination of all the above depending. Regards
