My room is likewise perfectly symmetrical for the front half of the room over 30ft long room. the front tweeters are 10'6" from the front wall, 10'6" apart and the the same distance to my ears at rested but upright seating position. This covers arrival times but I am very finicky when it comes to image focus. I can get very sharp focus with aggressive toe in but it sounds unnatural to me. Given that each frequency differs in directionality, it is important to me to head for coherence in terms of frequency balance. Aggressive toe in with the VR-9s make the upper bass too prominent. Gradually toeing the speakers out will balance out voices and instruments until I reach a perceived even balance from the highest note in the range to about 45 Hz. Tonal balance coupled with proper distance helps images to lock in better by actually keep the performers grounded as opposed to having all of their notes just floating in thin air as the foundation is as locked in as the higher frequencies. I know I've gone too far with the toe out when halos or auras begin to outline images, like how one sees after a long swim in a chlorinated pool. My end result is usually sharp but not photorealistic sharp. Images are slightly rounded at their outlines and ambient cues fill out the stage both horizontally and vertically oft times extending in front, behind and beyond the farthermost left and right speaker's position.
I do this because it makes it much easier to follow individual instruments, something very difficult if the frequency response of the singer/soloist has obvious bumps or dips that say, make a viola sound like a violin.
