Just as every instrument and voice have unique individual timbres, every AKG condenser microphone has its own unmistakable sound.
AKG large-diaphragm designs provide a warm, smooth, and silky sound that cuts through any mix, while AKG small-diaphragm designs deliver an extremely accurate, crisp sound. Every model has its own "personality". Therefore, producers use a number of different microphones in order to give their productions a personal touch. A single "universal microphone" could never reproduce such a rich spectrum of timbres.
We therefore recommend listening to and trying many microphones. Let your ears make the choice.
