Last weekend, I had the chance to borough a ECM-MS907 from a friend. It gave me exaclty the same result as the ATR25 which I have. As Sinamit is saying any pickup is overpowered by the circuitry noise, at low recording sound volumes. They both have virtually the same spec in terms of impedance (1K Ohm) and sensitivity (-54Db).
A company called Fel makes in-line pre amps which work with Plug-in power.Check:

Rode makes a video mic which looks promising, sensitivity up to -34Db and and only 200 Ohm impedance.

I might try and build the following pre-amp to go with my ATR25 over the weekend if I get the time:

Then there is the product of Maycom called the Mictube:

Anybody out there how has some experience with any of the above?
