Go to oktava.com and read the "about us" under the picture of Taylor Hohendahl. It pretty well explains the whole journey.
It doesn't explain why his prices don't seem like bargains, however, especially for those of us who have never heard any of his mics.
There's a really, really cheap medium format camera called the Kiev. You can buy it from any of half a dozen dealers, but quality control is a real crap shoot. However, there is one and only one dealer in Kiev cameras that charges twice as much as anyone else but makes sure that the camera you receive actually works.
I gather that the Sound Room is to Russian mics as Saul Kaminsky's Kiev/USA is to Ukrainian medium format cameras.
Does this help? (Or did you already know all this and were inquring about something else?)
Best wishes,
