No , maximum output is not always the answer .
Yes there is a balance and the optimum is usually achieved mathematically.
IMPEDANCE
The goal is always to properly match the impedances of the respective components in the front end.This will ensure a flat frequency response and widest useable dynamic range.
Namely matching microphone to input transformer ….then input transformer to input stage circuit ….
Input transformers vary a fair bit depending on the circuit they’re designed for.
Now remember transformers at their simplest are two coils around a core and only operate when there is an AC current running through them…. Now of course audio is an AC current.
An AC current running through one of these coils will make electrons flow through the other.If those electrons vibrate through coil #1 (primary) at a given rate…..they should encourage the same vibration in coil #2 because the coils are very close to each other.They are close but not the same.For every one turn on coil #1 (primary) there may be two or up to two hundred or more turns on coil #2 (secondary).This is called the turns ratio and is expressed thus 2: 200.
i.e 2 primary turns to 200 secondary. :D

Or to translate for us audio engineers, Plug mic in, turn up
Or to translate for us audio engineers,
Plug mic in, turn up knob, Equals good sound, hit records and headjobs by groupies.
um
all except that last bit.
