Mic Madness mics are good, the Sennheiser mke2 is the best electret omni for the price IMO. DPA and Sanken might sound better, but not for the $250 you spend for a pair of the mic madness mke2's.
The mke40's HLSC'1s are also very nice. They sound nicer to my ears than the AT853(c), but certainly lack in the bass department. They also handle a great deal of SPL with normal plug-in-power, making them a super option for stealth. Paired with a Hi-MD, you will be blown away...
As far as the accuracy argument goes, sure smaller diaphragm in theory are more accurate, but comparing SonicStudio's mics to DPA ?
I have used several varieties of Panasonic electrets, and indeed they can sound very natural/transparent. I even have a set of the old Radio Shack electrets that smoke my AT853's in the transparency department.
If I had more money than I knew what to do with, I would go with DPA if I was looking for a recording that sounded exactly like the source....
This is just my $.02, I am consumer/hobbyist, not a professional like some of you....
