Tri-Planar U12 Tonearm

A 12" tonearm that offers a 27% angular error reduction over smaller arms

Tri-Planar was founded by Herb Papier. As a young man, Herb played trumpet in amateur big bands and, later in life, owned a music store. In World War II, he received official recognition from the U.S. Navy for his expertise in chronometer calibration, a skill he continued to hone throughout his civilian career as a watchmaker. Eventually, Herb settled in Wheaton, Maryland, where he combined his talent for fine mechanisms with his love of music by creating one of the best tonearms the world has ever known.

The U-12 uses gimbal avionic bearings placed at record height, and a stiff carbon-fiber armtube. Like all Tri-Planar tonearms it is renowned for being utterly invisible, letting your cartridge truly shine.
