If it's anything I produced myself you'd just say I engineered
it to fail with XTC :-) Which indeed I could easily do...

I've been listening to XTC using all processors I know of,
in at least four very different rooms, and using all sorts
of source material. Some things sound rather well: e.g. binaural
recordings made using a dummy head, or using similar techniques
such as closely spaced omnis with some baffle or disk between
them. But those sound terrible on speakers if not processed,
so that is not the kind of material most people would encounter.

As to material produced for conventional speaker playback, some
of it produces a 'nice' sound, with a clear spatial effect, as
long as you are not trying to focus your attention on individual
sources or instruments. Which is something I can't avoid doing
being a trained sound engineer, but also something any musician
or critical listener will do at some time.

What almost certainly *fails in major ways* will be e.g.

- opera (or other forms of stage drama) recordings meant for
stereo listening (i.e. not the DVD productions which have all
the singers at the center to match the video),

- anything that has off-center bass (from ancient music
with double bass flutes to reggea),

- many organ recordings, which when XTC-ed produce an organ
that seems to be wandering all around, making me seasick.

Then I hope you will explain it.

In fact first order AMB has some perception merits that are
worse than for conventional stereo. Its great advantage is
that it is surround *wihout any preferred directions*. Which
makes for a very natural effect, even if the 'sweet spot' can
be small. But it's never as restricted as it is for XTC.

Some of his fans hate me because I (and some others) have pointed
out the limits of first order and moved on to higher order AMB,
which is where things really start to work even in real-life and
even in really adverse conditions.

There are none ATM that can produce full frequency range higher order,
and I doubt there will ever be. But we don't really need them either.
