The acoustic and psychoacoustic principles behind Ambiophonics are perfectly valid. Back in college I did some experimenting along similar lines, and even invented a passive inter-aural crosstalk cancellation system, but it was wildly impractical to say the least.
I don't doubt the claims made for very dramatic improvements in imaging, but if I understand correctly the downside is that your ears have to be in the right location for it to work - probably moreso than even the most sweet-spot-critical stereo setups. Thus I think an Ambiophonic setup would fit some people's listening style, but not others'.
