I believe you are making claims for the WAMM that Wilson is not.
The speaker is aligned at the listening position.
When you walk around the room, of course the sound changes, though it is much more like walking around a hall than in front of a pair of stereo speakers.
But head in a vice? Not remotely.
And if you break the alignment, the sonic quality of a WAMM is lost at the listening position and that ability to emulate walking around a hall is destroyed.
OK, maybe I am extrapolating the claims.
I understand and agree with the rest.
