Matched Pair, Different Positions: Can You Hear It?

How much can a small difference in microphone position affect what you hear? In this blind ABX test, two closely matched Neumann KM 184 small diaphragm condenser microphones were placed as close together as possible and recorded the same sound source simultaneously. Neumann microphones are known for their low production tolerances, making the KM 184 a good choice for this test. However, the microphones cannot occupy exactly the same position, so even a small difference in placement may affect the recording. Can you reliably hear the difference? Try multiple rounds and see how consistent your results are.
