Hi Greg

I had to google Chest and Charity Woods.  I see they are near Layer-de-la-H=
ey, probably an hour away from me. I have never been there.  I have visited=
 Abberton a couple of times.  The woods look quite extensive so might be a =
reasonably quiet place (other than the omnipresent aircraft noise that we a=
ll suffer from here).  Have you recorded there?

With regard to mic noise comparison tests I have several HiMD minidisc reco=
rders as well as the Marantz 661 and the Olympus LS-10.  All, more or less,=
 have the same pre amp noise.  It seems my two Sony NH1 minidiscs would sui=
t the requirements although an outboard phantom power supply would be requi=
red for the AT3032s.

I think the mic noise of the 3032s will be masked by the HiMD preamp noise.=
  Given the noisy environment we have in this part of Essex it would be int=
eresting to see if the MX391s self noise is an issue.  I see that the Shure=
 Wl183 (which apparently uses the same capsule as the MX391) is generally r=
egarded as noisy for very quiet environments.  Maybe the mounting of the MX=
391s on the small boundary plates will do a little better in respect of noi=
se.
