I just tried turning my head while listening to XTC. I can turn it more
than 45 degrees in both directions without destroying the stereo image.
So if turning the head is part of the localization process, it does
also work with XTC (to some extent).
XTC brings out a better and larger stereo image from conventional
stereo recordings, just by inserting a filter in the reproduction path
and by using two small frontal speakers (not four or more speakers all
around me as required by ambisonics). That's already impressive.
The problem is that people do not feel the need to set up speakers
properly and listen to a recent XTC. They are happy to listen on
internal laptop speakers, a stereo setup, headphones or just condem it
out of hand, based upon their 'knowledge'.
eg. http://www.avsforum.com/avs-vb/archive/index.php/t-1290580.html
I still don't know from experience if ambisonics is better than XTC
for other than practical and ideological reasons. I hope to have a
second epiphany with ambisonics, because it requires more investments
and efforts to install a working system at home. I only heard a few
minutes of ambisonics (rendered with the Harpex filter on a
horizontal/hexagonal speakers setup), and it was interesting...
I would be impressed if ambisonics could provide a better listening
experience from stereo and/or 5.1 recordings. Maybe it can; is there a
way to "up convert" non-ambisonics recordings to horizontal ambisonics?
