Why You Should Audition Your Mics 

i think auditioning mics is very important, in achieving an overall sound and character in the track, that you're after. i always do that. i only have one mic, so i audition that, decide it sucks, and then i use it. kidding, i have two condensers - cheap stuff, an nt-1a and a b1, and a dynamic - 58. in regard to my voice, i've auditioned them long ago, i've decided i like the b1 better, and i use that. i also prefer the b1 for acoustic guitars, though there's something to be said about the clean, very present sound the nt-1a has on those. so there it's more about what timbre the guitar should have in the track. i don't audition them anymore, cause i know what to expect, so i just pick the one that sounds closer to the intention.

the 47 sounded the best (smooth, big full, not shrill) on her voice.
