German disc mastering and lacquer cutting company, operating under this name between 1969 and November 2016. Then renamed to SST GmbH.
Founded in 1969 by Albert Brüggemann as a side job to his main occupation as sound engineer with the German public broadcasting company Hessischer Rundfunk.
Due to an increasing order volume, Brüggemann's wife Chris Brüggemann started cutting in 1971.
A second disc mastering studio was established in 1994; both cutting studios were equipped with Neumann VMS80 lathes.
After the Brüggemanns retired in 2011, the studio was owned and operated by Daniel Krieger.
