Supervinyl
Early MFSL titles were pressed by JVC in Japan on virgin 180 gram "SuperVinyl" LP discs. JVC originally developed this proprietary plastic compound in the early 1970s to reduce record wear on discrete 4-channel quadraphonic LP records. Supervinyl is a harder and more durable plastic than is normally used for LP records. The pressings exhibit a very low amount of surface noise, pops, clicks or other defects. Supervinyl remains a proprietary JVC technology and in the late 1980s JVC stopped production of the product. JVC has declined to license the use of Supervinyl to any other manufacturer, including MFSL.
