I have read about all the threads about the 104 and 105, but I still have some questions. Most posts refer to a loud stage. I am working on a relatively quiet stage with all IEMs. I am looking for Neumann mics for my vocal team at our church. Probably 3 or 4 mics in a row on boom stands. We are currently using Beta 87s. Would you go with the 104 or 105, or should I consider the digital models? If digital, do I need the digital option? I don't quite understand what I might gain from the D model.
