It is interesting how this more or less obvious point-
that localizing discrete sources and localizing all the(often multiple(
reflections that make up the whole spatial impression would be
one supposes related--has escapted the popular press especially
of the "High End" ilk.
They are all wound up about "soundstage" versus "image"
and claim eg that Blumlein stereo does image but it is spaced omni that
does soundstage and so on.
Apparently it has not occurred to people that if you
blur things enough to create "spaciousness" artificially
you will also blur the direct images, too. And the other way around
that if you reproduce where everything is correctly,
you will also reproduce where all the reflections come from.
That being said, there is some issue in stereo recording
about creating the illusion/impression of diffuse field,
which of course is considerably more than half the sound
heard at natural audience locations in a concert hall.
Most of the time the diffuse field is inadequately represented
in the recording--they are far too dry in effect through being too close--
so that one ends up trying to synthesize them from the listening room--
which of course comes out all wrong, if one is trying to get
a sound like a big hall. Thus one ends up with things like Bose
direct/reflecting and dipoles used not to reduce side wall reflections in
the listening room so much as generate back wall reflections and so on and
on and on, "soundstage" descriptions ad nauseum.

I know we normally think that increased directional resolution
corresponds to improved pin-point images, but thinking of it the
other way around - increased directional resolution corresponds with
with decreased 'accidental phantom imaging' is alsp true
absolutely. and i'm happy to welcome you as a honorary whippersnapper among
the ranks of the HOA snobs conspiracy :)
