The clarity and crispness of the e914 is fantastic. Now I am interested in the KM184's as well. I found the Neumann … e 914 - Recording Instrument Microphone - Studio,Live Performance - for Guitars, Grand Pianos, Cymbals, Percussion - Condenser Microphone - Sennheiser Discover True Sound - Top-quality products and tailor made solutions - sennheiser… The variable … The KM 184 is also a wonderful mic, but it's different. Typical of a Neumann, I found it had a slightly accentuated high end (not a bad thing) and more sensitive to low end proximity effect than the SM81. Doing some searched peaked my interest in the Beyer mc930 . I am either going to buy 1) a second e914 2) A pair of Beyer mc930 3) a used pair of KM184… I have used many, many microphones on acoustic guitars and the Sennheiser e914 is easily the best sounding microphone I have used. How would that mic compare to the Senn e914?
