Yamamoto Sound Craft YC-03S Low Impedance MC Cartridge

A limited reissue model that has refinished the former YC-03S to current specifications

The YC-03S is a model that extensively refines the formerly available low impedance MC cartridge to current specifications, reissued in a limited production.

The old YC-03S had ceased production due to difficulties in obtaining certain parts and materials. In this limited reissue model, while inheriting the core design concept of the ebony body, the generation system, cantilever, stylus, tension wire, internal wiring, and more have been revised to current specifications.

It is not just a reproduction; it is a revival model that reconstructs the powerful and realistic playback of the original YC-03S with modern specifications.

Vibration control centered on ebony body

The body uses African ebony. Ebony has been one of the materials that symbolizes our products, and in a cartridge, it is an important element that naturally absorbs the fine vibrations conveyed from the stylus tip.

Instead of leaning toward the sharp resonance of a metal body, the design makes use of the moderate internal loss unique to wood to achieve both the core of the sound and a natural texture. The stylus cover also uses the same ebony material, enhancing visual consistency.

1.0Ω Low Impedance MC Generator System

The generator adopts the Ortofon type, which provides stable performance. In the current YC-03S, the internal impedance has been lowered from 1.2Ω in the old model to 1.0Ω, and the output voltage is set at 0.2mV.

As a low impedance MC, the design emphasizes not only delicacy but also the density of generated energy, sound projection, and realism. Despite the low output, it aims to accurately convey the core of the music.

Solid Beryllium Cantilever and Micro Ridge Stylus

In the former YC-03S, a 0.26mm solid boron cantilever and line contact stylus were used, but in the limited reissue model, it has been changed to a 0.35mm solid beryllium cantilever and micro-ridge stylus.

The beryllium cantilever is a material that combines toughness and lightness. In combination with the micro-ridge stylus, it carefully picks up the fine information engraved in the record grooves, enhancing the attack, resonance, and spatial clarity of the sound.

While increasing the amount of information, it does not make the sound thin; with the ebony body and low-impedance generator system, it strives for playback with density and presence.

Strength provided by 0.12mm diameter tension wire

One of the major features of the YC-03S is the tension wire inside the cartridge. The tension wire is a key component located at the center of the vibration system that connects the cantilever, generator coil, and magnetic circuit.

While piano wire of about 0.06mm to 0.08mm in diameter is often used in typical cartridges, the current YC-03S uses 0.12mm diameter piano wire. Although revised from the 0.14mm diameter of the old model, it is still thicker than the standard specification.

Thin tension wires tend to increase compliance easily, providing extended high frequencies, but can weaken the sense of energy in the sound. By deliberately adopting a slightly thicker tension wire in the YC-03S, it emphasizes stiffness, core of the sound, and strong realism.

Internal wiring using 0.6mm diameter 6N copper wire

Even minimal wiring from the generator coil to the terminals inside an MC cartridge significantly affects sound quality. In the YC-03S, 0.6mm diameter 6N copper wire is routed close to the coil.

Compared to the extremely fine coil windings, the 0.6mm diameter 6N copper wire has a very large cross-sectional area. This design aims to transmit the energy of the generated signal without losing it, even in the smallest internal wiring.

Mounting rigidity provided by a base plate made of super duralumin

At the bottom of the body, a base plate made of super duralumin is installed. It indirectly reinforces the internal metal parts, such as the magnetic circuit, and increases the overall rigidity of the cartridge.

When attached to the headshell, this base plate comes into direct contact with the shell and reinforces the mounting area. By combining the natural resonance of the ebony body with the rigidity provided by the metal plate, it aims for powerful and well-defined playback.

Not a revival, but a reconstructed YC-03S

The YC-03S is a limited reissue model that inherits the name and basic concept of the old model while significantly reviewing its main specifications.

From solid boron to solid beryllium, from line-contact needle to micro-ridge stylus, and from a 1.2Ω to a 1.0Ω low-impedance generator system. Furthermore, with the 0.12mm diameter tension wire and 0.6mm diameter 6N copper internal wiring clearly stated in current documentation, both the vibration system and the signal path have been re-refined in terms of information, power, and presence.

While capturing delicate details, it does not thin out the sound, depicting the core and density of the music accurately. The YC-03S is an MC cartridge that powerfully and realistically brings out the energy inscribed on analog discs.

Refinement Content and Sound Tendency

The limited reissue YC-03S is not a simple revival of the old model. While retaining the design concept centered on the ebony body, the cantilever, stylus, generator system, tension wire, and internal wiring have been significantly reviewed.

Compared to the old model's 0.26mm solid boron/line contact stylus, the current specification adopts a 0.35mm solid beryllium/micro-ridge stylus. It has evolved in a direction that clearly reproduces the attack and resonance of sound while capturing finer details.

The generator system is a low-impedance type of 1.0Ω. The output voltage is relatively low at 0.2mV, but the design emphasizes the density of the generated energy and the sense of power. Rather than being delicate and slender, it is an MC cartridge that focuses on the core of the sound, its drive, and realism.

The 0.12mm diameter tension wire is an important element that supports the body's strength and power of the sound. Furthermore, the 0.6mm diameter 6N copper internal wiring makes the design emphasize the core, power, and realism of the sound from both the vibration system and signal path.

The YC-03S is not an MC cartridge with a wooden body that only delivers a soft atmosphere. It is a cartridge with a distinct character, combining the natural resonance of the ebony body with the energy characteristic of low-impedance MC, and the high level of information provided by the beryllium cantilever and micro-ridge stylus.
