I can't afford to experiment either. I've two very old, fairly small
magnaplanes. And don't expect to get more. In any case to do this one
right would require building a room just for it.
From my own listening and experimenting with the magnaplanes I would
say that the imaging (in stereo) is far better than you'd expect. I've
heard a regular style surround magnaplane, and the imaging there was as
good as the source material. My original comment was that the
magnaplanes could very well be worthwhile to try with your 4 channel
surround. I've not done that, obviously, so cannot predict for sure the
outcome. I expect it would be very good, better than with standard speakers.
It could be that the area source is so enveloping that you don't need as
precise a point for good imaging. It is different, as you say a
different ball of wax. I can observe how they behave, I can't get into
the math of why.
One of the problems I'd have with your system, from my own experience,
is that I'd hear it as 4 point sources. I always hear regular speakers
that way, even more so with the current crop compared to, say, the 70's
speaker systems. And you are recording sound coming in from all
directions, so it should not be just 4 points. It's part of what got me
interested in the magnaplanes in the first place.
