"The Church of Scientology (aka, the Scientologists) have at least two DMM lathes in their mastering studio (which is most likely located in their Golden Era Productions facility in Gilman Hot Springs / San Jacinto, California) - but they do not work on projects other than their own (they transcribe L. Ron Hubbard’s speeches onto disc and place them into time capsules along with hand-cranked turntables. Sometimes truth is stranger than fiction).
"Europadisk in New York City (based first in Manhattan, and then moving in 2000 to Long Island City) was the last mastering studio in the USA to offer Direct Metal Mastering on a commercial basis - but it ceased operation in 2005, and its lathe and other DMM mastering equipment were sold to the Scientologists at auction."
