Also some very cool still photos from inside the Grado offices:
Thanks for sharing the link to the pictures. Very interesting as I've always heard of their presence within a browstone building in Brooklyn.
In the pictures, I noted the following:
* The lathe appears to be housed in a red box with the glass window. I suspect they are using a CNC machine to cut all of the mahogany cups as well as the inserts for the PS-1000, and PS-500.
* The time clock on the wall for punching in / punching out during the start and end of work only had 5 time cards in the slots. Does Mr. Grado use a card? My guess is yes. This operation is "old school" pretty much all of the way with the exception of the parts (headbands, gimbals, etc.)
