The speed of sound in air is always varies depending on air pressure, elevation, temperature and humidity.

Huh!

All I know is that when I hear something or many things, I am hearing them all at the same time. The brain can distinguish between the time arrival between the ears, but if only one ear is working, it cannot distiguish from how far away a sound originates, since the sound waves detected by the ear are simultaneous.

I'm confused.

"The speed of sound in air is always varies depending on air pressure, elevation, temperature and humidity."

Atmasphere,

Yes this is true and I beleive I tried to indicate as much with my addition of "(Ignoring long term changes in temperature, humidity etc.)"

I'm assuming that the elevation, temperature etc. is fairly constant in your listening room.

The bottom line is that your audio system must play to your brain – not your test equipment.
Roger,
That is not the point of the argument. Besides any properly set up rig with decently designed equipment, will do just what you describe or do you seriously maintain, that most of the gear we have at home is but " a poor attempt to recreate a sound event riddled with phase errors" ? Forgive me, if I laugh.
