Thank you for the information. It is interesting to have found a unique set of mics and to have bought three consecutive units over the course of a decade. I do prefer the KM 84 to the KM184 and always assumed it was the capsule but comparing the transformerless km84a makes it clear that both the electronics and capsule of the km84 contribute to the sound I prefer, and simply switching the capsule won’t give you a km84.
