Hi David,

Not quite up to anechoic chamber standards, but under several duvets here a=
re the spectrum plots:

An mp3 raised to -3dBfs that illustrates the different noise shapes is here

and the orignal file here:

It's going back to B&H tomorrow.
It may be a one off below spec mic, but I think I will hang fire getting a =
replacement until I hear more field reports from others.

All the MKH 80X0 series seem to have slightly worse noise than the older MK=
H X0 mics.
I wonder if they have taken miniaturization too far and traded off inductor=
 Q or PLL phase noise to get the size down.
It would be interesting to see schematics of the new mics.
