http://www.schoeps.de/en/products/cmc6You are getting too focused on the term amplifier. The Mixpre does have (pre)amplifiers. The Mixpre can provide phantom and amplify incoming signals but doesnt have the circuitry to provide the charge which the capsule requires in order to produce a signal. The amplifier in the CMC does.
Your options are )several of them at least):
MK41v + CMC > Mixpre (phantom and microphone in)
MK41v > KC5 cable > CMC > Mixpre (phantom and microphone in)
MK41v + CMC > External Pre-amp like V3 > Mixpre (no phantom, line in)
MK41v > active cable (some connector, TA6 or KCY etc) > Nbox [ 9 volt ]> Mixpre (no phantom, line in)
MK41v > active cable (some connector, TA6 or KCY etc) > baby Nbox > Mixpre ( microphone in preumably)
MK41v > active cable (some connector, TA6 or KCY etc) > PFA > Mixpre (phantom and microphone in)
MK41v > active cable (some connector, TA6 or KCY etc) > IPA [ 12v or 5v ] > Mixpre (no phantom, line in)
MK41v > active cable (some connector, TA6 or KCY etc) > IPA [ Phantom ] > Mixpre (phantom and microphone in)
The Nbox and IPA and CMC and PFA all potentially affect the sound, yes...
Put another way, capsules cable and deck are not sufficient. You need an inline device to provide the charge which the capsule requires in order to produce a signal. That inline device may also have circuitry to amplify the signal before it exits the device. A device that does both would typically be used in conjunction with the line in of the recorder. A device that only powers the capsule would typically be used in conjunction with microphone in on the the deck. The inline device can use diffferent power sources depending on design.
A Nbox powers the capsules and provides fixed gain sufficient enough such that you can use line in on the deck. I believe a baby Nbox powers the capsules but doesnt have the circuitry to add gain.
