I am looking for a good pair of small diaphragm cardioid condensers to use professionally on small classical ensembles and solo piano. What mics would one generally use for this purpose? Right now I am looking at Neumann KM184, Earthworks SR77, AKG C451B and Elation KM201. What does everyone think of these mics for this purpose? Could I expect comparable results with less expensive mics such as AT4041's or Rode NT5's? Are there any other mics (with the exception of DPA and Schoeps) that would work well?
