The JVC X-1 is a high-performance MM (Moving Magnet) type cartridge developed in the mid-1970s, with distinct technological advancements aimed at enhancing audio reproduction. Priced around ¥ 25,000 when it was released in 1975, the X-1 features a 0.15 mm square Shibatar needle, designed specifically for superior tracking and delicate sound reproduction. The cartridge is characterized by an output voltage of 2.7 mV at 1 kHz and a robust output balance within 1.0 dB. Separation is impressive, rated at 25 dB or more at 1 kHz and 20 dB or more at 30 kHz. Its electrical impedance is 2.2 kΩ, with a DC resistance of 470 Ω. The compliance measurement stands at 12x10^-6 cm/dyne at a frequency of 100 Hz, indicating its capability to handle a wide range of audio frequencies, from 10 Hz to 60 kHz. The cartridge's design includes a lightweight and rigid bell-rim cantilever to minimize vibration loss, supported via a one-point suspension system to enhance clarity and diminish distortion. Furthermore, it employs a Sum Cobalt magnet, which allows for stable output and a lighter overall weight. The laminated core constructed from thin permalloy material optimizes the magnetic circuit for better efficiency and reduced loss. Overall, the JVC X-1 is engineered for serious audiophiles looking for precision in high-frequency audio reproduction.
