In December 2003, we released the revolutionary low impedance MC cartridge "Eninent" with the theme of "Low source impedance, high output energy...!"

After that, it has been 7 years since the lineup included "Eminent Solo", "Hyper Eminent" and "Eminent GL".

For Mysonic Lab's MC cartridges, we believe that "low impedance and high energy output" is the basis of AC theory in signal sources, and is the basis for obtaining a wide dynamic range, so we pursue even lower impedance. ``Ultra Eminent Bc'' was completed after challenging the challenges of stacking wires, small windings, and high output.

Normally, a small number of wire turns leads to a decrease in inductance and output voltage, but it greatly improves the phase disturbance inherent in windings (coils) and contributes to improved resolution. But output energy is also required.

The magnetic properties of the core material support the conditions for this, and this is why the high saturation magnetic flux density (BS) and initial magnetic permeability (μi) are important "keys."

In conventional low-impedance MC cartridges, even if we introduced powerful magnets and new material components to obtain high energy output, we were unable to obtain the desired effect, and as a result, we had to rely on the number of turns of the coil. Therefore, the internal resistance has no choice but to increase to 5Ω to 6Ω.

However, as a matter of course, the increase in the number of windings inevitably increases internal loss and expands the phase shift "lag".

In order to solve these problems, "Ultra Eminent Bc" introduces the newly developed ultra-Hi-BS/ultra-Hi-μi core material "SH-μX" and a powerful magnet called neodymium #50. However, without causing magnetic saturation, we achieved an unprecedentedly high efficiency energy output with an internal resistance of 0.6Ω and an output voltage of 0.3mV.
