For me, it isn't a matter of whether or not holographic imaging is heard live; live is one thing, recordings another. If soundstaging is inherent in a recording and your system isn't reproducing it, what else is it missing?
It was Harry Pearson and The Absolute Sound who made imaging and soundstaging a priority, to a degree beyond my desires. I will admit that the first time I heard the great depth in a recording (Holst's The Planets, Boult on EMI, iirc) reproduced by a system (a complete Decca/ARC/Magneplanar Tympani system set up by Bill Johnson), I found the sound of a tiny little triangle being played way at the back of the orchestra thrilling. It actually appeared to be further away than was the wall behind the speakers!
As it is for others, my priority in reproduced music is lifelike timbre, especially that of singing voices. Of them I cannot abide any degree of added coloration. Next is transparency---hearing though the equipment back to the recording itself. The one aspect of imaging important to me is that of instrument size and height, though those are not exactly the same; you can have either without the other.
