I currently own a MM in ear binaural mike which I love. Looking for a step up model that I can use to record into my MZN-10. I record mainly choral, classical and pipe organ. Not sure what to go for. I run my mike through a denecke AD20 then into minidisc. If anyone could possibly help me with the next step up would be greatly appreciated. Don't want to spend much more than around $250.00 Peace
