No point in discussing basic physics, a self noise of 19 dB(A)

input of the preamp. Unless I botched up the the c

It's not so much the microphone, but what you connect it to: because of the
relatively low sensitivity, you really need a low-noise pre-amp. I use a Metric
Halo ULN-8, which works extremely well with the TetraMic. The ST450 outputs at
line level, so mic pre-amps are not an issue. And of course,
I've used the TetraMic almost exclusively for outdoor 'nature' recordings,
including much at dead-of-night.
I've never had a real problem w. noise from the mic, (in reality, nature very
noisy) - my problems have almost all been with RF and I would love a balanced
solution.

On 05/11/2013,
Just a short note about noise.
While the ST450 is slightly quieter than TetraMic, in practice, TetraMic
noise has never been a problem when Recording Music .. even in very quiet
studios.

Just to echo the others, really. The TetraMic has its faults, but at the price,
it can't be beaten, although it looks as though the Brahma (prices are on the
Kickstarter site, Eric C) will run it close. I'm hoping for a demo model quite
soon, at which point I'll be able to do comparisons.
