As the cartridge tracks the record it also has to move the tonearm, side to side and up and down. It does this in order to position itself, as closely as possible, on the mean line of the groove. Failure to do this accurately will result in loss and distortion of the musical signal the cartridge is to extract. To assist the cartridge in this cumbersome task, the reference tonearm utilises a unique bearing design both in the horizontal and vertical planes. Using several hundreds of microns-thick Kevlar threads provides silent, ultra‐low friction movement of the arm without any stiction.
