Considering the OP asked about chopped Naks, not the stock models. Does this change the voltage requirements at all, or is it just imperative to keep the cables short?

They are the same.  The capsule sees this voltage, and it doesn't matter if it's from a full Nak body with the ER 206 or from the chopped nak and preamp.

And to specifically answer the OP question, the 8'ish volts from the newer 9100 should be enough voltage.
As Seth said, you will probably need another gain stage.

How much gain does the 9100 provide?  I knew the nak 300s were light on output, but are they really in that much need of additional gain to put more gear in the chain?  Why not just boost in post? 

I should note that I have never used the Church pre, but am curious.

The Naks are very low on the output around -38 at 114db at 1k that's not very much output if your at a show that's say 100 db you would be looking at significantly less then -38 so I would definitely recommend a preamp for these mics. That being said my 9100 puts out 23 db of gain at full output and the noise level at that output is
-98dBA.

Chris,

Can you please advise the  output level/impedance spec of the 9100 ? 

ie  The Nak mx-100  is 100mV/560 ohms and does not require me to add any gain in post or on my recorder.

Thanks
NAK CM-300's  -> CP4's,CP-3's,CP2's,CP1's ->SonyD5
NAKCM-300's ->  CP4's,CP-3's,CP2's,CP1's ->MX-100-->NJB3
NAK CM-100's  -> CP4's,CP-3's,CP2's,CP1's ->SonyD5
NAKCM-100's ->  CP4's,CP-3's,CP2's,CP1's ->MX-100-->NJB3
Sony PCM-M10  (looking at stealth mic options)

sorry for the thread hijack.

I was also wondering if a 9100 or ca ugly would power my akg ck91 "3wire batt box" set up.
How many volts do the akg's need to function properly?

Church will customize the 9100 with mini-XLR inputs if you ask nicely, which allows for 3-wire mic setup (AT853 etc). I don't think this option is available on CA-Ugly because of size constraints.
I can't say anything about modded AKG caps because I never used any, but drop Chris a PM and he will sort it out...

For the information, the Nakamichi MX-100 have a maximum gain of 500 (54dB). 0.2mV of input gives 100mV of output. With chopped Nakamichi CM-300/CM-100, I think you will need a gain of about 30-45dB while recording acoustic music in an normal setup. I have no idea of what gain is needed for stealthing amplified music
