The MP13 uses a servo balanced instrumentation amplifier for studio grade performance in a small package. This equates to a 40db better common mode rejection ratio (CMRR) than transistor inputs used by most companies on mic inputs. It also means much lower distortion. The clearer sound with more "air" puts the MP13 in a class with much higher priced units.
