I had hard times trying to get good signal from my mics too. In fact it was the most challenging part for me, because I am not any good in analog schematics. Check out this link: http://www.epanorama.net/circuits/microphone_powering.html Also you can find good scheme for measurement mic here...

No, I measured once. I am going to do some additional measurements this weekend, wanna try to get big virtual room for movies and separate layout for 5.1 movies

No, I had not. I get very good result with first try.

Hi! As I promised, posting pictures of my diy microphones and amp:
