9TT

About the 9TT

The Ikeda 9TT is a moving coil (MC) phono cartridge designed for true playback without unnecessary coloring. Its body is precision machined from a solid billet of aluminum alloy to securely fix the power generation structure and prevent resonance that can cause sound muddiness. The cantilever features a double layered duralumin pipe construction to reduce moving mass and increase stiffness, minimizing warping effects on sound. The stylus chip is a solid diamond with a line contact shape, which accurately picks up sound sources as originally recorded. The cartridge uses a highly efficient permalloy core, low impedance coils (2.0 ohms at 1kHz), a strong neodymium magnet, and an optimized magnet yoke to deliver sound with excellent linearity and minimal coloration. It has a frequency response of 10Hz to 45kHz, channel separation over 27dB at 1kHz, and channel balance within 1.0dB at 1kHz. The recommended stylus force is 1.8 grams ±0.2 grams, and the output voltage is approximately 0.16mVrms at 1kHz, 35.4mm/sec. The cartridge weighs about 10 grams. Each unit is carefully fabricated and precisely aligned to capture the subtle details and beauty engraved on LPs and SPs, making it especially suitable for chamber music and string quartets where timbre definition is critical.
