You need LOTS of very closely aligned speakers and the software will take a while to install/learn, then rendering the channels also takes time if you do it that way. The "holosonic" point source next to the ear is my holy grail - I havent got it yet - but I am told IRcams system can do this. I have heard stories of weird phase effects next to the ear in other systems, and have got that working - but thats not quite the same. The truth is you could probably get something more spectacular going with quarter the amount of speakers and Vbap.
