I believe equipment alone won't do it. The room dimensions, treatments and positioning are major contributors; a major rabbit hole, should you choose to go down it. Jimbatkh
That's because the speaker interacts with room. If the speaker is less dependent with room acoustics, equipments alone will produce more holographic soundstage.
My sound system displays spectacular "holographic soundstage and images." If anyone wants to experience it, I welcome anyone. Just PM to me.
