i am considering buying a matched pair of Neuman 18x microphones and i looking for opinions and/or recommendations on which set to get. i'm going to be using them for drum overheads, stereo program recording (live bands, concerts, stage productions) and for instrument recording like guitar, violin, woodwinds, perecussion, etc. i also have a pair of SM-81's that i've used for hi-hat, guitar, violin, percussion. The Neuman's are going to replace a set of Octiva 012's (used primarly for drum overheads) that are just ok and i'll will keep them but i really want to upgrade and i have the budget. so my questions are: - should i go for the cardioid 184's or the omni 183's? i'm leaning towards the 184's. - are there other mic's in that price range that i should consider? thanks!
