i am impressed you could tell the microphone angles! in fact the front pair=
 are about  60 degrees, facing each other.

i have just taken apart my brand new zoom H 2 after about five minutes of r=
ecording. the aim is  to remove those microphones (which are actually quite=
 interesting) and replace them with four tsb 120s arranged as a soundfield =
mic, mounted on a stem coming out of the zoom. i will have then the world's=
 cheapest high quality sound field system (200 dollars + 4 * 20 dollars). t=
he zoom can be mounted on a stand, it probably can even be put at the focus=
 of a telinga. think of it as a mic rather than a recorder.

I own a Zoom H2 and the mics sound quite amazing for the price
(meaning: realtively uncoloured), but they are of course not very
silent. I would say the selfnoise is around 23 to 30 dB(A). Something
you should know about the mic-setup is that the front mics, which are
angled at 90 degrees, sound more like 60 degrees. The rear mics,
angled at 120 degrees, actually sound like 90 degrees. It's a pretty
amazing recorder for the money (180=A4). A positive thing to mention is  =

the ease of use. The Zoom H4 is a bit quirky, but this one is simple
and straightforeward.

The holophone uses 6 DPA 4060's afaik, so watch out, the self-noise
of those mics is around 23dB(A)! Not particularly low for recording
