Well i was experimenting with my 4061 and measured the voltage of my DAD6001 and DAD4099 phantom>microdot (latter is the same functionally but has a rolloff) with and without a mic attached. Both were 8.1V with no load, but much lower with mic attached. i tested 3 of the "legacy" 4061s and 2 of the "CORE" 4061s. Voltage under load was 2.4-2.5V with the legacy mics and 2.65-2.75 with the CORE series
I also tested my d:vice, which is ~4.95V with no load, but was ~2.5V under load of legacy 4061s, ~2.725V under load of CORE 4061s.
hmmm. so i decided to try to power CORE 4061s with my A10 on PIP
A10 voltage with no load ~2.8V
with one mic ~2.4V
with 2 mics 2.2-2.3V (for both CORE and legacy 4061s)
i dunno, voltage is a little lower than the official DPA solutions, but sounds fine to me. here is a sample of me holding the two CORE 4061s about 8-12" in front of a monitor played at moderately loud volume (takes a few seconds to get into position, end of track i back up a bit)

further testing:
Tested with Roland R07, 2.4V with legacy 4061 connected:

Tested with Microtrack II, 2.45V with legacy 4061 connected:
https://soundcloud.com/user-760596491/4061-mtii(MTII is 2.75-2.85V with CORE 4061s connected)
the A10 sample above was with a CORE pair of 4061s, the R07 and MTII tests above were with the legacy versions of the 4061. Im not a huge fan of the MTII (reliability) but both the R07 and MTII seem like a safe bet with voltage very similar to the official DPA powering options
apparently the MMP-G cables that run the full size caps, should work fine with either the microdot adapters and d:vice, ergo, they may also be able to be run from PIP handhelds as well... will know soon. Specs say they only draw 1mA (as opposed to 1.5mA for 406x) so thats a good sign
it seems like the 4061 CORE versions have a slightly lower current draw compared to the legacy versions on every device tested apart from the A10. maybe the A10 has a different voltage/current control strategy and has a more constant voltage over a wider current draw range.
