About the Premium 4D SB2
The ZYX Premium 4D series uses an advanced moving-coil generator with a balanced eddy-current elimination mechanism and cryogenically treated coil wire options in copper, silver, or gold. The Premium 4D SB2 variant pairs this generator with the heavier silver base plate, raising the cartridge's net weight to about 7.9g, which makes it suitable for medium-mass tonearms rather than high-mass arms. In the copper-coil (Cu) configuration, the cartridge uses 6N crystal copper coil wire for its specific tonal character. It features a solid boron cantilever and Micro-Ridge solid diamond stylus, with an output of approximately 0.24 mV and an internal impedance of 4 ohms. The cartridge is discontinued and no longer in current production.
