Perfect 3D imaging, haha, then I have to laugh. A little tip about what drugs you took today: either take more or less.You're confusing mediocre sound illusion with precise 3D imaging which implies you haven't actually heard 3D. I didn't experience it until I got to own a high-end store and play around with hundreds of speaker designs.
First of all, it's impossible to reproduce, say, an orchestra with two sound sources. In a concert hall, reverberation times of 1.5-2.5 seconds are normal; if you try it at home, it sounds terrible. At home, people aim for between 0.3-0.5 seconds, which really ruins things. Perfect doesn't exist, but it can get close to reality. It works pretty well with a wave-field synthesis speaker—I'd say 98% of the time. Unfortunately, it's not yet affordable, and it's currently being tested at the Musikhochschule in Detmold, Germany.
If you're in Germany, get tickets, listen to a concert, then go to the WFS room and listen to it again. It sounds incredible.
