Sonic X4 Cartridge

The HYPER SONIC X4 is a unique moving coil cartridge with a Multi-Layer Core. Combined with a new, stronger magnetic alloy shaped for better focus of magnetic flux, fewer coil-turns could be used for a given electrical output  (only 0.2mV output with 4 ohm impedance).

A stiff diamond cantilever was chosen. This is inserted into a hardened titanium sleeve to transfer every micro-deflection generated by the micro-ridge stylus to the moving coil. This gives the Sonic X4 the ability to trace every minute detail of the grooves cut in the lacquer by the sharp cutter of the lathe. The generator is rigidly held in place relative to the interface to the tonearm with a titanium superstructure. The body is made of shot-peen surface hardened titanium. Three tungsten inserts are strategically placed to enhance the inertia stability of the cartridge and improve resonance damping.”

Praise for the X4:

The X4 has been praised by most everyone who has had the opportunity to hear it.
