I don’t know much about binaural recordings using a Neumann head. But when it comes to recordings made with normal microphones, they must always be positioned much closer to the sound source to represent a similar sounding result as a listener listening position further away. The problem is that the microphones will pick up a much higher ratio of room-reflected sounds which our hearing will “filter” out at the same distance, microphones simply don't work as our hearing and will not make a distinction between reflections and direct sounds.
