Founded by master cartridge maker Mr. Yoshio Matsudaira in 2004, the goal was to pursue and develop the ultimate dream cartridges. Mr. Matsudaira has been a highly sought after designer of high performance cartridges, with a client list that has included respected brands such as Koetsu, Air Tight, Miyabi, Luxman, Supex and Audio Craft. His unique SH-μX high flux / high permeability core material is one of the few genuine breakthroughs in cartridge design in the last fifty years. Only with the development of SH-μX was it possible to achieve an unseen level of performance with the lowest internal impedance and the highest output.
