I was looking at that Cooper Pre that dirk's helping sell (cause I need a preamp like I need a hole in my head...) and it was pointed out that the amp could be modified to pump out P12 instead of 12T. My beyers will handle P12 (the 900 series in general, maybe others as well), and the Schoeps CCM series and CMC6 bodies will as well. What others out there will?

Lots of AKG condensers use 12-48V phantom (sometimes described as 9-52V).
The Sennheiser K6 series also use this as do several other electrets of theirs.

Yeah, the 451s will (xnay the 480s or 414s). Thanks.

Here is a very interesting and probably little known summary about schoeps CMC5/CMC3 that David Satz summarized a few days back...

interesting. I was trolling the schoeps site last night and didn't see the CMC3, but remember reading literature in specs about it. Didn't even think of it last night though. Thanks.
On an unrelated note, the rolloffs of various bodies is equally interesting.

Actually, the AKG 460s also run 12-48, and the 414 ULS also I believe. The 480s and the 414 XLS and TL require P48 exclusively, I think.

yeah, I couldn't find stats on the 460s easily enough this morning. The 4 414 models they have on their site currently (XL2, BXL2, XLS, and BXLS) all are stated as P48 only. :-\

Here is a link from the AKG site to the manual for the 414B-ULS
http://www.akg.com/mediendatenbank2/psfile/datei/19/C414B_ULS4055c233c018f.pdf
And a link for the 460B-ULS
http://www2.akg.com/mediendatenbank2/psfile/datei/50/C_460_B4055d332d6126.zip
Both are P12-P48, unlike the 414 XLS and 480B-ULS that are each P48 only.

Just an FYI, when I brought this up before I was told otherwise by dsatz.

I'm not sure what professional level is though.
I guess maybe it could've been my wording of most.
However quite a few according to spec will run on it.

newplanet7, I'm sorry if my earlier reply seemed dismissive, but I think it's important for people to be very clear that this is a serious issue. You're right, there are many good microphones, and even a few professional-quality ones (some Schoeps and AKG models, for example) that will run well on 12-Volt phantom powering as long as the available current is enough.
But in the earlier thread you said, and I quote, "Most mics can run well under 48v without issue." I had to dispute such a general statement, as I think you understand now. A manufacturer's powering specifications don't have an arbitrary amount of "wiggle room." The tolerance limits for the four standard powering methods (P12, P24, P48 and T12) are listed in the ISO specification. Those are the limits which the microphone manufacturers expect to be maintained, and they're not very wide.
Even though some microphones do allow wider tolerances than the standard, those wider tolerances don't carry over to other microphones in general. Even a single manufacturer (such as AKG) can have some microphones with wide tolerances and others with narrow tolerances.
With professional microphones, guessing or relying on intuition or dumb luck about how to power and connect them is a particularly bad idea, because most of the high-end manufacturers are pickier about powering than the run-of-the-mill far Eastern electrets are. (Even an AKG with "9-52 Volt powering" still needs enough current, and with some of their models, that's more than many low-end power supplies can provide.) So people who extrapolate from their experience with lower-end microphones are apt to be caught in a trap, and that's the situation I'm trying to prevent.

No worries David.
I realized my words were misleading in the other thread.
