Most speakers will disappear better if you:
1. Pull them well out from the rear wall 1- 2mts. and at least 1mt from the side walls
2. Reduce toe in, so you can just see the inner side of the speakers from your listening position.
3: The biggie: get rid of all the image and depth sapping racks, equipment, and anything else from in between your speakers, put them on the side or behind you, this will open up a whole new world of image and depth for you, more than anything else.
Neville Thiel rip (from Thiel an Small speaker design fame) told me this ages ago and he was so correct.
That’s when you go to HiFi Shows the demo’s that have the best image and depth are the ones with nothing between the speakers, because they know.
