Oyaide HPSC-35

Overview

Together with today's headphone boom, HPC Series of Oyaide Electric Co., Ltd., which quickly recognized the importance of headphone cable to users. The lineup that conforms to the sound quality and user needs is accepted by headphone users all over the world, and the series cumulative shipment number has actually become a hit series exceeding 50,000 in fact. However, along with the end of the PCOCC-A conductor, the HPC Series will be discontinued sequentially to regret it. 
With full, it is adopted as 3.5 stereo mini attachment method which is adopted in many headphones such as Audio Technica ATH-MSR 7, Sony MDR-1A, the first of the new headphone cable "HPSC Series" of Oyaide Electric Co., Ltd. in 2016 The corresponding "HPSC-35/63" will appear.

Characteristic
The key technology of "HPSC-35/63" is in "Precision Conductor 102 SSC" and "Silk". For the cable conductor, "Precision Conductor 102 SSC" is adopted in place of the PCOCC-A conductor of the previous model. "Precision Conductor 102 SSC" is a conductor for high-end audio cable produced by Oyaide Electric and has already earned high praise around the world. The conductor configuration is a 7/7 / 0.089 rope twist excellent in flexing resistance, its thickness is 0.3 margin affordable. From delicate high frequency to powerful low frequency, we deliver delicate headphone output faithfully without stagnation. Also adopt "precision conductor 102 SSC" for the shield, making it a flexible spiral shield. Adopted "silk interposition" which has cushioning property and static electricity suppressing effect in inclusions. Also cover the cable exterior as "silk jacket". These synergistic effects greatly reduced touch noise without compromising flexibility. The chic cable color of mosaic style by white and black matches any headphone without any discomfort. HPSC Series leading the future headphone market. It is the beginning of the new era of headphone cable.

Precision Conductor 102 SSC
HPSC Series is a new series replacing the HPC Series. The key technology is in "Precision Conductor 102 SSC" and "Silk". For the cable conductor, "Precision Conductor 102 SSC" is adopted as a new material to replace PCOCC-A. As "high-end audio cable", Oyaide Electric's "Precision Conductor 102 SSC" has already earned high praise around the world, but this is the first time to adopt it for headphone cable. The conductor configuration is a 7/7 / 0.089 rope twist excellent in flexing resistance, its thickness is 0.3 margin affordable. From delicate high frequency to powerful low frequency, we deliver delicate headphone output faithfully without stagnation. Also adopt "precision conductor 102 SSC" for the shield, making it a flexible spiral shield.

Pure silk filament
For intervention, adopt 100% pure silk filament that does not electrostatically charge with low electrostatic capacitance. When a signal flows in the cable, weak vibration occurs, and substances charged with static electricity cause corona discharge due to the vibration. To solve this problem, mount the silk filament. In addition, she covers "100% pure silk jacket" on the exterior of the cable. These synergistic effects greatly reduced noise without compromising flexibility. The chic cable color of mosaic style by white and black matches any headphone without any discomfort.

Original terminal connector
Plugs specially designed to give your own identity. The material of the metal part adopts brass which satisfies European RoHS directive. To the contact part which is also called the main point of signal transmission, silver plating of 1.5 μm thickness was applied directly, and 0.3 μm thick rhodium plating was applied to the surface. This prevents corrosion of contacts and contributes to improvement of transmission characteristics.
The outer shell of the outer shell also reflects the craftsmanship of Oyaide Electric. Cutting is performed carefully one by one by NC machining, Verilochrome plating is done to finish as well as the camera lens after precisely carving knurl. In addition, these plugs are joined to the cable by the audio special solder "SS - 47".
Pour aesthetic sense to detail and create superb quality. This attitude is the theme that OYAIDE electricity will continue. For every dense and polite finish, the essence of Japan's unique craftsmanship will live.

Acoustic special solder "SS-47"
 
For soldering of wiring, we used "SS-47" acoustic exclusive solder of oyaide electric original. Regular solder is about 99.9% (3N) tin purity from the cost perspective. "SS - 47" further raises purity to eliminate impurities to the limit, and adopts high purity tin of 99.993% (4N) or more. In addition, silver and copper were blended for the purpose of improving conductivity and preventing eating of solder. Moreover, in the case of ordinary alloy solder, the blending ratio of silver is 3 - 3.5%, but "SS - 47" put in a spiritual quantity of 4.7% how much. In addition, silver has a conductivity of 1.7%, which is the next highest in conductivity, among metals. Due to this compounding ratio the conductivity has dramatically improved and succeeded in setting the eutectic point to 217 degrees.
Of course, these compounding ratios are not judged only by numerical data and workability. I think that the highest priority is given to sound quality to be inscribed as a solder for audio, and it should be appropriate. "SS-47" was created by a hearing test that was not repeated several proto models of various mixing ratios.
