I'm here to pick technical nits ... I have neither Senn MKH mics nor Rode m=
I do have an Edirol R-1, and a SD 722 on order.

Actually, there is a polarizing voltage with respect to the backplate.
It's just from a permanently trapped charge in the backplate, and not
a voltage from an external source.

This is wrong. The diaphragm is *not* a variable resistor. It's a variabl=
capacitor just like any other condensor mic. And there is a polarizing vol=
it's just that it's AC (and RF frequency AC, at that). So the average
polarizing voltage is zero, but the RMS voltage is non-zero. But yes, the
diaphragm movement does change the frequency of a resonant circuit.
