New analog world with tradition and technology

Accurately picks up the sound of the groove and does not degrade it

Description

We chose blue-and-white porcelain for the cartridge body from the perspective of Chinese culture and sound. We tested the sound quality of more than 10 types of porcelain carefully selected from among the many types of porcelain in China, and after comparison and examination, we finally chose blue-and-white porcelain, which has a density close to that of aluminum and has the best sound. The "dragon," "bird," "tiger," and "turtle" represent "protection," "good fortune," "power," and "longevity," respectively. All cartridges are assembled by hand by experienced engineers.

The performance of a cartridge depends primarily on a combination of factors, including

1. handling of resonance generated during tracking

If the resonance generated by stylus tracking fails to achieve damping or cannot be absorbed, it will bounce back to the stylus via the cantilever and interfere with normal stylus movement, causing sound quality degradation. Therefore, we design each cartridge to be priced according to its performance and select the appropriate materials and design to achieve a vibration isolation effect commensurate with the cartridge's performance. Therefore, the more expensive the cartridge, the higher its performance in eliminating the effects of resonance caused by the materials of its body and structural components.

2. selection of suspension tension and damping stiffness

Different cantilever materials require different suspension tensions and damping gaskets, which must be adjusted for optimal dynamic response. They are also important indicators for determining the resonant frequency of the stylus. The ultimate goal, of course, is to get the stylus to the proper needle pressure so that the groove signal is picked up quickly and accurately and does not resonate in the audio frequency range of 20 Hz to 20 KHz.

3. cantilever length selection

Cantilever length also affects resonance frequency and response speed.

4. selection of number of coil turns and coil material

It is related to the internal resistance, inductance value, and output level of the cartridge.

5. selection of magnets and magnetic circuit design

Different types of magnets have different magnetic fluxes, and a high flux magnet can be used with a small number of coil turns. Conversely, a larger number of coil turns is required.

6. stylus tip structure selection

Different stylus tip structures have different contact surfaces with the grooves on the record disc, affecting the sound resolution. The better the tip structure, the more detailed the sound. The order is conical < elliptical < line contact < super line < micro ridge.

In other words, our cartridges are made by selecting and combining the above six aspects based on a comprehensive evaluation of price, performance, and function.

Aluminum cantilever and oval-shaped natural diamond stylus

"Turtle" MC cartridge was the first cartridge released by Jasmine Audio and is the most cost-effective Jasmine Audio cartridge. The cantilever and stylus are made in Japan and offer excellent tracking and sound performance.

Innovative resonance suppression and cantilever suspension construction

Warm, comfortable, clean and dense sound.

Blue-white porcelain body, oriental musicality

Blue and white porcelain is the perfect audio-visual combination, introducing Chinese cultural characteristics and pleasing to the eye and ear.

Review

Jasmine's MC cartridge, the B&W Porcelain series, is the company's high-end series. I purchased the Byakko, which uses sapphire for the cantilever and a Shivata needle for the stylus. There are four models in this series, the Blue Dragon, White Tiger, Vermilion Bird, and Genbu, which are named after the four gods. The Blue Dragon is made of boron, the White Tiger of sapphire, the Vermilion Bird of aluminum, and the Genbu of an aluminum pipe cantilever. The body is made of a settee with a bare vibrating system inside. As can be inferred from the shape, the Porcelain series was designed with a great deal of care and aggression, and the sound is also very impressive.As is common with all Jasmine products, the sound far exceeds expectations for the price.*Mr. Nagai, Bakoon Products
