Yamaha's YSP approach relies on bounced sound. You need a shoebox-shaped room with hard walls and ceiling to get the best effect. It is highly room dependent.
But most virtual surround uses beamforming and phase shifting to create the 3D illusion. This works even if you have no walls i.e. in an open field.
Also, the Nakamichi does have side-firing drivers, so it is using reflection to widen the front soundstage.
Most of the soundbars with virtualization rely on reflection to create the audio delay as perceived surround effects, especially those without a single rear speaker.
Beamforming technique (especially yamaha) has very narrow sweet spot which is always the issue. For a 3-seater you can hear different sounding on 3 different seats. Heard it personally at my friend house and the effect was really average and somehow a bit strange.
While nakamichi is not the cleanest in terms of setup but I believe discrete surround speakers can provide the most reliable and consistent surround effect regardless on the shape of the room. Coming as an owner of traditional 5.1 system, I feel the ultra 9.2 is doing really good job to bridge the gap between convenient setup and true immersive surround.
