Imaging differentiation of the sound sources is not the holographic volume distribution of each sound source and the soundstaging three dimensions vary and are not fixed, the holographic perception is recording dependant and is related to the abilities of the speakers in a acoustically controlled room to give the best recording specific translation..The speakers design must be good to begin with... but it is not enough... At least with normal AVERAGE speakers under 5,000 bucks... With very costly speakers i never experimented ...The MBL seens able to give holography with minimal acoustic control...With my average but good speakers Mission Cyrus, holographical expeerience was possible only after a complete control of my room... Impossible in a living room... Probably the MBL speakers made it possible in a living room optimally organized with no heavy acoustic devices and treatment by the virtue of his specific omnidirectional design... bUt it cost at least 100,000 bucks... 😁😊 It would be for sure more clear and more detailed than my Mission Cyrus vintage paid 50 bucks..,.
For sure PERFECT holography exist with virtual room acoustic with Dr. Choueri BACCH filters... Read about it to understand WHY this is so...here too it is not a trick which will distract you from music at all... Many people think that way because they had never experience holography really...
Holography is not A PARLOUR trick, but an acoustically controlled phenomenan by a set of acoustic ratio for each different room... Digital processing can do it but because i never bought a good digital processing system i dont know...The DIGITAL PROCESSING of dr. Choeri BACCH filters will not degraded timbre experience and will gove holographical translation of each recording as it is set ...it is not a trick, choueri is a classical music lover and a physicist acoustician... He dont sell tricks..
My experience was with acoustic control of the room with Helmholtz resonators grid and "sound lensing from the speakers" with foldable screen and the right balance in reflective waves and direct one and the right balance of absortion/diffusion reflection ratio... i also use distributed tuned resonators to improve mechanically by some mechanical crossfeed between speakers helping the localization around the room... But if the recording process is bad no speakers/room can improve it only making it more interesting and less disgusting soundwise... But even with the best recording in the world if the relation between speakers and room is not optimal, there will be very poor holography...
Holography is not a trick it is an acoustic phenomena studied in acoustic laboratory .. Studied with electronical and/or mechanical parameters too....
