Hi Keith!
Let's hope I have better luck with THIS reply!
Firstly, in reference to the CAD 179, I do have one of those, and bought it=
 with the intention of making up an M/S rig, but never did get around to it=
. The original idea was to use it with my MKH60 which I sold complete with =
Rycote basket and fluffy for a silly price brrr!  Secondly, I also still ha=
ve my HD-P2. This is pure luck, because I bought it in a bit of a state, wi=
th repair work needing doing, and because it looks a bit rough I didn't bot=
her to sell it, even though it now works perfectly. A month or two back a b=
rand  new sealed case for it came up on eBay at a silly price, so I bought =
it, and at least it looks better now! The only other mic I'm likely to buy =
sometime is the AT BP 4025, which Jan brought to my attention with one of h=
is marvelous recordings. I still have a couple of ME66's with K6's, but one=
 of them is faulty; must sort that out! Lots of things to keep me happy for=
 a while anyway.
I went out yesterday to see if I could find some Crossbills to record; I fo=
und them, but had equipment problems. I'd taken the Nakamichi collection wi=
th me and had the long shotgun on it. It soon became clear I there was a pr=
oblem which made all three mics useless! The birds were there with a nice f=
lock of Siskins, but the means to record them wasn't!! On inspection this m=
orning, it turns out that the problem was with the lead which came with the=
 mics. Clearly at some time the previous owner had replaced the lead and fo=
r some reason hadn't connected the ground in the XLR! When I'd previously t=
ested it, it must by chance have been just touching?! For some stupid reaso=
n; I'm guessing old age, it didn't occur to me to use the internal mics! Su=
ch is life
Cheers
Max
