WFS is stereo++. The sweet spot is much wider, and if you move around you hear a convincing illusion of getting closer/further from the virtual sound sources.
But it's pretty much the state of the art, and impossibly expensive for home use. I'm finding it hard to imagine how it would be possible to distribute sound to various points around a room with negligible leakage or interference.

I'd like to try that between my face and a guitar amp.
I always use a 4-speaker 4x12 cabinet even for practice just because the sound is more complex; the interference patterns change subtly as your head moves. That keeps the tone fresh if you're at it for several hours.
Imagine a "hologram grille" on a simple little combo amp with a 10" speaker. Maybe it could affect the tone in cool ways.
How would this work?
