The June 2000 issue of "Recording" magazine had a write up on these mics. They said it was an "excellent Microphone, but the quality control at the Russian factory is pretty bad". "Make sure you listen to it in the store before you take it home" They went on to say: "The real prize on the Oktava... is the omni capsule". Anyway, for what its worth, that's what was said about them. If you can find a copy of that issue, it might be worth your while to read it.
