Bias for mics does not "improve the sound" of a mic. Rather, bias makes 
electret mics work (you'll get no sound from them without bias), and can 
cause problems with dynamic mics. At the very least, bias can cause 
distortion with dynamic mics, and at worst might damage them. This is 
NOT a topic for experimentation. If you want to know more, I suggest 
that you study how mics work.
