I read a lot of things written here as if they are gospel. I will give you my own experience.
I have a holographic sense of space that reaches beyond my speakers and with excellent and focused imaging. I have substantial equipment between my speakers, and have no room treatment beyond an area rug and acoustic tiles in the ceiling. The room is built on a concrete pad, and thus the floating wood floor is firm. The speakers are ATC SCM35’s placed two feet from the wall and about 10 feet apart in a 20 by 20 foot room. I do not separate my cables, but I have a really excellent equipment rack of wood with steel points in steel cups separating each rack level. I do have a tube preamp, but I get the same sense of imaging depth with both a C-J tube amp and my tweaked-up, 45 year old Ampzilla, and whether I am streaming or playing vinyl.
So, while room treatment may help and equipment rack placement may help, you can get to this level of imaging without it.
