To Chris-
I record loud shows, quiet shows, and not shows, so if I'm going to go to the trouble to build a mic (and I am) I'd like to see the full noise floor potential of a 1/2in. capsule.
Um, as far as THAT products go, they have mic preamp ICs and line drivers and (really cool) transistor arrays, but all of the above are BJTs and thus have inadequate input impedance to buffer the output of a bare electret.
How did you get transsound (or whomever) to manufacture you custom capsules? That is pretty incredible.
To Richard-
Chris' two-wire approach is certainly elegant, especially for devices which use a conventional stereo mini-plug (thus unbalanced) plugin power arrangement. However, the MR-1 uses dual mono (balanced, mini-trs plugs with plugin power and, as I stated, I'd like to use all my pins. Call me neurotic. On a more serious note, I operate in some terribly noisy (in every sense) environments, and long cable runs are often extremely useful.
I'm building a coincident mic for a couple of reasons, one of which is mono compatibility in a stereo device. When I want to work with omnis, I have a pair of DPA4060s I'm pretty happy with. I do, however, need to build a battery box for 'em since I was previously powering them with a Mic2496, which I'd like to part with.
