In London, the demo clip was played using one set of speakers and then played again using the other set. The audience was then invited to say if they thought the first playing of clip was Atmos Speakers or ceiling speakers and same for the second playing of the clip.
In the first demo I attended, nobody could reliably guess which set was which.
Note that this is not to say they were unable to differentiate one from another - they could not tell which
set was being used. I think several people could hear that there was a difference but were unable to say with reliability that they were hearing A or B.
In the second demo, only one person was able to determine accurately which was which (me) - but that was because I was the only person present in the audience who had had Atmos speaker experience at the first demo and knew what to listen for.
What to listen for is this: Atmos speakers create an impression of slightly more spaciousness and diffusion at the slight expense of precision. Ceiling speakers create more precision, with slightly less diffusion. Neither is 'better' or worse than the other - they are both good, but different and it will depend on user preference which one is chosen.
It may also produce a different result in different rooms, with different ceiling heights, and different speaker setups in the ceiling. It may be possible to reduce the differences in presentation to negligible proportions, with some judicious speaker placement, speaker type etc.
Is there a point to this line of discussion?
