RE: The human ear has openings oriented forward and rather large

Well, recording technology is far beyond use of a few omni's If the goal is to pick up pressure variations in an acoustic space most accurately then a good omni is the way to go. However, in most recordings, even live venue recordings, the two voltage vectors (waveforms) that make up the left and right channels bare little to no resemblance to the pressure variations that appeared at your ears during the same performance - or even the signals from any of the instruments played. The recording engineer and or producer sit with a few to more than a couple dozen signals that were recorded from microphones and directly from electronic instruments placed at various locations in a hall and near the stage. Even signals recorded earlier or later (overdubs) are added to the mix. The sound produced is created in the production room, from the artistic compilations of these signals as listened to over the recording studio's monitor speakers (or a set of head phones).
It is only by the will and imagination of your mind that you get a "observation" of a live performance when reproduced over your mega buck cables and hi-fi equipment from this otherwise contrived pair of stereo voltage signals from these skilled recording engineers.
