A mic preamp isn't an effect, at least not with regular use, it's an amplifier. The quality lies in how it behaves in this regard, the noise floor, speed etc. Amplifying a mic through a low quality preamp, then running the result through a profile of a good preamp makes little sense. You will just paint the bad source in a different colour.
Of course, if you want to use a mic peamp's distortion characteristics as an effect, it makes more sense.
interesting topic !

Maybe there is someone, who can compare a mic preamp to the same preamp as a profile 
I don't want to use a low quality preamp first and then a good quality preamp after. My question was to use the Kemper as good quality preamp only. The Kemper profiles most of the existing guitar amps and the question is has the Kemper the ability to profile a good studio mic preamp.
I guess what Trazan means is that you can't hit the KPA with a mic signal, it has to be pre-amped via... a preamp. So, the final result would depend on the weakest part of the chain.
OTOH, if\once you've got a high-end mic pre, the KPA becomes redundant\useless
Hope this makes sense
I guess Akkan will put a mic which don´t need phantom power (e.g. Shure Beta 58 a.s.o.) in the Kempers input. Even this microphone types are sounding very much better with a studio preamp. Not every user owns a good quality studio microphone.
Unfortunetly i don´t have a high quality mic preamp - otherwise it would tried to make a profile. Anyone else?
I profiled my mic-pres some time ago, Universal Audio, Chandler, Mindprint...
Do a search for "pre_" on the rig exchange to find them.
Thank you for sharing - I´ll give them a try!
Btw: I have two very cool profiles from you in my setup, it´s the H&K Thirty. Thanks again for it!

Right.
I was rather referring to the mic's output level compared to a guitar output level: it's more or less 1/10 (about 20 mV Vs. 200 mV?), and I am not sure the sound you'd get would be the best possible w/o a pre.
Refloating this thread: anyone used the Kemper to record vocals connecting a microphone directly to the KPA?
I've just tried it as an experiment. WAAAY too low level on a dynamic. You'd have to go through some kind of preamp anyway. I actually have a tube mic with it's own power supply, that should give enough output. I might try it some time. But I'm not expecting earthshattering results

I asume this could be more expensive than a reasonable good pre ampifier.

I got mine for cheap - but other than that, I agree It would be more as an experiment.
