No, not too early, cause nowadays there is no reason to make a mic input 
noisy. You can presume it is good (low noise) enough.

The cheapest little chip amp has a better noise performance than the best 
mic amps 10-15 years ago.

The design challenge is to make a mic preamp running on 1/ low voltage, 2/ 
low current consumption, still 3/ good headroom and 4/ low noise.

All "walkman" size recorders that I know of sacrifices the headroom in 
favour of low noise.
