We think that the best audio balance for the bandwidth is the way to go.
Some people go thru 10 microphones to try and get that perfect match of balance with their Voice, Rig and Mic.
Really all you need is a full range mic and an EQ to get the same effect.
Of course the extra units all add their sonic signature to the mix.
It's allot of fun, not to mention work, to get that perfect balance.
Take care,
