Dość znana sprawa.The V-15 Type V marked the introduction of a proprietary "ultra-thin wall beryllium" stylus shank with a stiffness-to-mass ratio several times that of other cartridges on the market. In 1998, Sony Music Entertainment selected the Shure V15VxMR to transcribe 80 years of Columbia Records and Sony Music masters and recordings. In 2008, Gramophone Magazine awarded the V-15 an "Audio Choice" designation for outstanding performance and value. Due to the scarcity of the raw materials required to manufacture V-15 cartridges, Shure discontinued the series in 2004, and in June 2009, the last remaining V-15 stock was purchased by the Library of Congress.
