The "gimmic" in stereo is not really a gimmic but a limited implementation
of the theory. The problem, even with two mic recording is that the 
"crosstalk" occurs twice. Once when the recording is made (which is the
same as when you listen to a performance live) and again when you listen
to the recording. There has been a fair amount of research on this phenomenon,
mostly found in AES (Audio Engineering Society) publications. It has found
its way into the commercial market through Carver. The term "holographic"
applied to this is a misnomer (probably from the need for a marketing term).

As with most Carver ideas (at least from what I gather on the net) the
idea is based on fact and will probably be debated forever until others
discover it. It would be interesting if some of the recording people did
the processing on the record side. The implementation would not be as
good probably but it would improve the imaging somewhat. It is possible
that in some of the "better" recordings people comment on that either
some of this was done either by design or by accident.
