Thanks Jeff.
To add to the question list: if one were to them w/an M6K, is there a cable adaptor that would allow them to be plugged directly into an iriver?
And any further info on whether an R09 WILL run them adequately mic-in?
Thanks again boys - apprecaite the responses
I'm not sure exactly what you mean. With the MMA6000 the 4060 mics have microdot connectors, and the cable out of the MMA6000 is 1/8" stereo. I suppose you could get a dual-microdot to 1/8" stereo adapter to use them directly into an iRiver (if the iRiver can power them, which I don't know to be true), but I have not seen one of these.

I'll second the MMA6k suggestion. Very nice sounding, well built unit built especially for the 406x mics. You can put it in one front pants pocket and the recorder in the other. It is signifigantly larger, heavier & made of metal vs. the R-09 though.
Since the preamps in the R-09 seem to be pretty decent at lower gain levels, I've also wondered about eliminating the MMA6k for high steath situations that do not require as much quiet gain. By the specs, the R-09 doesn't have sufficient plug-in power to power the 4060/4061's itself. In light of that, I've been thinking about (4060>dual-microdot to 1/8" stereo adapter>batt box>R-09 line in) as well. Or perhaps a custom batt box with microdot inputs and eliminate the adaptor. Either way the cable or batt box with the microdots would need to be custom built.
I don't know of anyone who has tried to power the 4060/4061's directly with the R-09 but would be curious to know if it works and how much the performance is reduced if it does. DPA makes a lower voltage version of the 4061, but not the 4060 (dont' know the number off hand, you can find it on the DPA site) that could potentially be powered directly from the R-09, but that's uncharted territory. Uncertain if that version works with the MMA6k. It's designed for use directly into lower voltage wireless systems.
You can get a little better deal on the DPA stuff from some of the smaller vendors recommended on this site & you'll support the smaller buisnesses that support us in turn.
Good luck!
