Hey Chess......found it - from the SOS review on the M177 &179.......
"A lot of the budget condenser mics available today are manufactured in the Far East, almost regardless of whose badge appears on the body. It is worth noting, then, that CAD construct their own Optema capsule designs in a special clean-room facility within their factory in Ohio in the USA, and install them in microphones manufactured entirely on site."
Now what they don't say is whether the Optema capsule has anything to do with the M179. It would be pretty misleading of them if not, which I certainly wouldn't put past them.
