TechDAS is the prestigious house brand of Stella Inc., the premier distributor of high-end audio in Japan, founded in 2010 by legendary audio engineer Hideaki Nishikawa (1941-2023) who revolutionized analog turntable design through his visionary approach to pneumatic and vacuum technologies. Building on his extraordinary career that began at Stax Ltd. developing electrostatic headphones after receiving his mechanical engineering degree in 1963, followed by his influential tenure at Micro Seiki as technical department manager where he developed the legendary SX-8000 turntable (1981-1990), Nishikawa established Stellavox Japan (now Stella Inc.) in 1989 as an importer of high-performance audio gear before launching TechDAS to fulfill his lifetime dream of ultimate record reproduction. Based in Itabashi-ku, Tokyo, TechDAS specializes in the Air Force series of ultra-premium analog turntables featuring groundbreaking air-bearing technology that absolutely isolates the rotating platter and record from vibration, combined with vacuum LP hold-down systems that clamp records onto the platter for unprecedented sound quality compared to conventional analog turntables. The company's flagship products range from the statement Air Force Zero ($450,000) to the more accessible Air Force V ($19,500), with the Air Force One, III, and IV models available in both standard and Premium versions, all handcrafted in Japan with subtle craftsmanship that elevates music enjoyment to an art form. Under the brand philosophy of 'Digital Analog Supremacy' (DAS), and now led by current CEO Tsutomu Horikawa (Stella Inc.) and Kohei Ando (Zephyrn Inc.) following Nishikawa's passing in June 2023, TechDAS continues advancing analog audio technology while serving as the ultimate expression of Japanese precision engineering for discerning audiophiles worldwide who demand the finest in vinyl reproduction.
