Top Wing Cybersound Group is a Japanese high-end audio equipment manufacturer founded in 2017 by three industry veterans who previously worked at Nakamichi Corp: inventor Hiromu Meguro, designer Yasuhiro Noguchi, and business professional Koichi Sasakihara. After leaving Nakamichi in 2016 when the company was repositioned as a lifestyle brand following its acquisition by a Chinese business, the trio formed Top Wing to continue pursuing their passion for high-end analog audio reproduction. Based in Tokyo at 1-10-2-1102 Sakae-cho Higashimurayama 189-0013, Top Wing specializes in premium phono cartridges using advanced technologies and innovative materials, building on the legendary expertise of Hiromu Meguro who created the famous Grace F-8 and F-9 cartridges in the early 1970s and contributed to iconic Nakamichi products like the TX-1000 and Dragon CT. The company's product portfolio includes the Blue Dragon, Red Sparrow Suzaku, and Seiryu cartridge series, all featuring coreless straight-flux designs with precision aluminum cantilevers and line contact styli engineered to capture sound information that existing cartridges miss for superior soundstage reproduction. Working in collaboration with First Mechanical Design Corp. (led by designer Yasuhiro Noguchi), Top Wing utilizes ultra-high precision laser technology to manufacture all components including needles, cantilevers, assembled magnets, coils, and dampers, ensuring exceptional analog audio performance that continues the Japanese tradition of excellence in high-end audio equipment for discerning audiophiles worldwide.
