The only, truly holographic imaging I ever experienced was at Acoustic Image, back when Eliot Midwood has his storefront down on Ventura Blvd. I was so taken by it that I stood up and tried to move around the images. They stayed stable but lessened in intensity as I neared them and tried to go around them but the ones further away stayed put. It was the most surreal experience I've had and like @mapman mentioned, the MBLs come pretty darn close. Listening to them takes me back to that day at Acoustic Image.
It must have been the synergy of the gear, room and speaker placement but it was a joy to behold. So, no, one cannot have too much of a holographic event as it just completes the magic needed to thoroughly enjoy the music.
All the best,
