What does Holographic mean to you?

Holographic means that the music isn't rooted to the speakers, but instead seems to be originating from specific areas where the musicians and singers are arranged throughout the soundstage of your listening room -- especially between and outside your speakers -- in the best
cases, there is air between them and you can imagine some closer to
you and some further away -- the proverbial deep and wide soundstage.
But, holographic means the musicians and singers appear throughout the soundstage almost like holograms.

To me 'holographic' means 3-dimensional. A 'normal'stereo image sets musicians between the speakers frome left to right. Imho a 'holographic' sound means there is also depth and height, like the real world, but there just not fysically in your room.

To me "holographic" in this respect is even more than 3-dimensional: it lets you hear the different layers of musicians. So you can hear exactly who's playing BEHIND another instrument and even further behind - AND above, too! For example I have a Guitar Duo-recording in which one guitarist is sitting on a high chair. And you can hear that his sound is coming from a higher position than the other guitarist who's on a normal chair. But that's what I basically expect of gear with the name "HighEnd". Everything else ist just Stereo imho.
