'Holographic Sound Stage?'

Dress circle level, just right of center, Carnegie Hall.

I have pairs of speakers in 5 rooms off two different source systems and get a holographic sound stage to varying degrees with each. It mostly has to do with how well set up the speakers are in the room for holographic sound. Setups in only two of these rooms are highly optimized for holographic soundstage. The other three are more general purpose so I have to compromise somewhat in those.

The best holographic soundstage comes from my large OHM F5 series 3 speakers, which are in my larger L shaped listening room.

NExt is a pair of Dynaudio Contour 1.3 mkII monitors in my smaller 12X12 listening room.

Third is a pair of Triangle Titus XS monitors in my somewhat large family room (lower volume listening mostly there due to high volume limitations with those small monitors)

Fourth is my smaller pair of OHM 100 series 3 speakers in my wife's sunroom, where setup options are limited and acoustics are most challenging.

Fifth is an old pair of custom modded OHM L speakers that I run in my unfinished area on occasion. Casual litening only in there so large holographic soundstage is not of concern.

I also run a pair of small Realistic Minimus 7 speakers outdoors on my deck in warm weather. HOlographic soundstages do not generally happen much outdoors with no room acoustics, so these do not do much of anything in that regard but still sound quite good.

Funny,

The setup I heard years ago in Jim Smith's old Audition store in Birmingham Alabama with Magnepans was one of the best ever, including holographic soundstage. Speakers were well out into the middle of the room, well away from walls.

Maybe the thing is that often best placement for holography and soundstage (generally away from walls) negatively affects bass levels/tonal balance and dynamics. Reconciling the two is often constrained by speaker design/type used and may require tweaks to room acoustics as well. Speakers that are designed to work full range well away from walls might have an advantage, though certainly very good results can still be achieved with speakers closer to walls, as long as sound smearing early reflections can be avoided.
