This is a common fallacy. This is why speakers sound worse than
headphones. The ear uses this imformation to determine that the sound is
really coming from two point sources, the speakers. headphones do not
have this limitation.

So headphones aren't point sources? Perhaps you'd say what they are, then?

Hence the placement of the speakers with respect to your ears adds an
extra'layer' of time information and affects the relative
time/amplitudes at the ears in a way headphones do not.

however Im sure you'll agree that a recording designed for headphones
would have that signal recorded into the right track.

thus the ability to image is not independant of what your source
material is.

Forget loudspeakers or headphones. Clamp your head rigidly and try
positioning live sounds with your eyes closed. Then try again without the
clamp. The small natural movements of the head helps position sounds by
measuring tiny phasing and level changes. This can't happen with
headphones.

show me a pair of speakers that can create the, admittedly unusual,
situation of having a sound entirely in one ear and not at all in the
other.

Absolutely. Headphones create unnatural positioning effects. No sound in
reality could only reach one ear.

2. A binaural recording, designed to be heard through isolated left-right
channels and processed for headphone listening at recording time.

But a binaural or dummy head recording doesn't provide infinite separation
of left and right. Common units use omni mics separated by a plastic disc
which will only provide separation of perhaps somewhat under 20dB, and
only at mid and high frequencies.

For the avoidance of doubt, the OP stated that headphones could never
produce as good a stereo image as loudspeakers. I disagreed.

Perhaps you'd define 'image'. If you mean the ability to purely identify a
left and right signal, then you're correct. Ping-pong, anyone?

But for the nuances of a soundstage, you're totally and utterly wrong.

Err, who's talking about using room properties as a trick?

What would you call it? the sound isnt originating anywhere near where
it was originally (I suppose technically that makes all recording a
trick, but at least with a typical stereo setup sounds are *really*
comming from in front of you...

In a good room with good speakers listen to a good recording made with
a good coincident pair. You\'ll clearly hear what\'s on the front of the
mics and what\'s on the back.

I didnt deny the trick works...
