In detail, I think, yes it is different.
It is designed for a certain angle and distance
which are different at least from RGs stereo dipole
where the speakers are close together in front of the listener.
But I do not see any reason why the whole thing could
not be easily programmed up. After all, any analogue
(determanistic) process can be digitally modeled
as accurately as one wishes.
I am unaware whether anyone has done it.
It is fun to play the Sonic Hologram--I pull mine
out every one in a while,

Subject: Re: [Sursound] cross-talk cancellation used in binaural sound
reproduction
I have a Carver C-9 Sonic Hologram unit that I bought on Ebay for about
$80. It's a nice little demo piece, but limited in its application.
That said, it's biggest problem is noise. Of course it's all analogue
and built around -10 dbm levels. And all those capacitors are now very
old.
Has this sort of thing evern been implemented in code, like a VST
plug-in? Ideally it would be nice to have it available within the
plug-in architecture of the Logitech Squeezeserver that we use for
casual audio playback. There are even limited implementations of room
correction done in that manner.

You can still find the devices around(they were
crosstalk cancellation processors).
They work really well, if you do not
mind sitting really still in one spot
(which of course you are going to have
to do for any such system with only two speakers).
And the nice thing is the Sonic Hologram sounds good-
it does minimal damage to the music.
It is interesting--sort of tells you where the industry was
and still is on surround and so on--that Martin Colloms
writing about the Sonic Hologram in HiFiNews
says that it definitely makes stereo better [and potentially
much better] but that it is just too much trouble...
