About the F9 Ruby
The Grace F9 Ruby is a premium high-output moving magnet (MM) phono cartridge renowned for its exceptional sound quality and musicality. It features a ruby cantilever, which is second in hardness only to diamond, providing minimal resonance and flexing for precise energy transfer from stylus to generator. The stylus is an OCL (line contact) type made from a top-shelf ruby cantilever, designed to deliver the finest high-frequency tracing of inner grooves. The cartridge offers a flat frequency response extending beyond 50 kHz, with an output voltage of approximately 2.6 mV at 5 cm/sec and 1 kHz, and an impedance of about 1.7 kΩ. It requires careful setup and more frequent cleaning to maintain optimal performance. The Grace F9 Ruby is highly regarded for its vivacious, detailed, and dynamic sound with excellent channel balance and low cross-talk, making it a favorite among audiophiles and broadcasters alike.
