> For less perfect results you could just set up measurement microphones in the right position and then convolve the result with a Head-Related Transfer Function. This sounds interesting. Could you get to near-perfection by simply increasing the number of microphones used? Also, could using cheap microphones be compensated by using more of them? |

No. Ears are (kind of) point sinks. Which is why dummy head stereo works so well on headphones - it's literally recording the sound that would usually go into your ears, as opposed to normal stereo, which records something that's usefully but rather distantly related to what goes into your ears.
Two microphones are enough for that.
A side point is that everyone has a slightly different HRTF, so it would be interesting to hear what you'd get with a neutral point sink recording convolved with your HRTF.

No again. Cheap microphones add non-linear distortions and have a limited and inaccurate frequency response. If you use more cheap microphones you just get more of the same.
