With the development of portable and desktop audio, the demand for 3.5 stereo mini to RCA cables to connect PCs, high-resolution players, and smartphones to audio equipment has been increasing year by year. Oyaide was quick to recognize these needs and commercialized the HPC-35R in 2009, which combined all of our cable technologies and was applauded by many audiophiles.
As time has moved on and the wireless environment has begun to flourish, there is still much demand for cables that allow users to enjoy high-bit/high-rate sound sources with even better sound.
The signal and shield conductors are made of "102 SSC," a precision conductor developed by Oyaide Electric. It faithfully transmits audio signals from delicate high frequencies to powerful low frequencies without stagnation. In addition, the "100% pure silk interlayer" and "100% pure silk jacket" with cushioning and static electricity suppression effect significantly reduce noise caused by vibration and static electricity. The luxurious mosaic cable color matches any audio equipment.
The 3.5 stereo mini plugs and RCA plugs are specially designed for the HPSC-35R and plated with silver/rhodium, and are carefully soldered by skilled craftsmen in Japan using SS-47, a solder specially designed for acoustics. The HPSC-35R is a premium 3.5 stereo mini to RCA cable that is the result of the highest level of luxury in every aspect, from the cable to the plugs.
The key technologies of the HPSC-35R are the 102 SSC precision conductor and silk. The cable conductor is made of "Precision Conductor 102 SSC" instead of PCOCC-A conductor of the previous model. The "Precision Conductor 102 SSC" is a conductor for high-end audio cables created by Oyaide Electric, and has already received high acclaim around the world.
The conductor configuration is a 7/7/0.089 rope strand with excellent bending resistance, and its thickness is a generous 0.3 scale. It faithfully transmits the delicate headphone output from delicate high frequencies to powerful low frequencies without stagnation. The shield is also made of "102 SSC," a precision conductor, and is a spiral shield with excellent flexibility. For inclusions, "silk inclusions" are used, which provide cushioning and static electricity suppression.
In addition, the cable exterior is also coated with a "silk jacket. The synergistic effect of these materials has significantly reduced touch noise without sacrificing flexibility. The chic white and black mosaic cable colors match any headphones without any sense of discomfort. The HPSC Series will lead the headphone market in the future, ushering in a new era of headphone cables.
The HPSC Series is a new series that replaces the HPC Series. The key technologies are the "102 SSC precision conductor" and "silk". The cable conductor is made of 102 SSC, a new material that replaces PCOCC-A. The "precision conductor 102 SSC" developed by OYAIDE ElEC. as a high-end audio cable has already received high acclaim around the world, but this is the first time it has been used in headphone cables.
The conductor is a 7/7/0.089 rope strand with excellent bending resistance, and its thickness is a generous 0.3 scale. It faithfully transmits delicate headphone output from delicate high frequencies to powerful low frequencies without stagnation. The shield is also made of "102 SSC," a precision conductor, and is a spiral shield with excellent flexibility.

For the interconnections, 100% pure silk filament is used, which has low capacitance and is not charged with static electricity. When a signal flows in a cable, weak vibrations are generated, and materials that are charged with static electricity will experience corona discharges due to the vibrations. To solve this problem, silk filaments are mounted. In addition, the cable exterior is also coated with a "100% pure silk jacket. The synergistic effect of these materials has greatly reduced noise without sacrificing flexibility. The chic white and black mosaic cable colors match any headphones without any sense of discomfort.
Specially designed plugs to give it a unique identity. The metal part is made of brass that complies with the European RoHS Directive. The contacts, which are the key to signal transmission, are plated directly with 1.5 µ-thick silver plating and then with 0.3 µ-thick rhodium plating on the surface. This prevents corrosion of the contacts and contributes to improved transmission characteristics.
OYAIDE craftsmanship is also reflected in the outer shell, which is carefully machined one by one by NC machining, knurled precisely, and finished with The plugs are also plated with berrichrome, just like camera lenses. These plugs are joined to the cables using "SS-47" audio solder.
OYAIDE aesthetic sense is poured into every detail to create the finest quality. This attitude is the theme that will continue to run through OYAIDE. The essence of Japanese craftsmanship resides in the meticulous and careful finishing of every detail.
Plugs and cables are soldered with "SS-47", a lead-free silver solder specially designed for acoustic use. Ordinary solder has a tin purity of about 99.9% (3N) due to cost considerations." SS-47" is made of high-purity tin that is 99.993% (4N) or higher, eliminating impurities to the utmost limit. In addition, silver and copper are added to improve conductivity and prevent solder from being eaten away.
Furthermore, the ratio of silver in a normal alloy solder is 3 to 3.5%, but in "SS-47" a whopping 4.7% is used without hesitation. In addition, SS-47 contains 1.7% copper, which has the second highest conductivity among metals after silver. This ratio dramatically improves the conductivity, and we succeeded in setting the eutectic point at 217 degrees Celsius. Of course, these blending ratios were not determined by numerical data and workability alone.
We believe that sound quality should be the top priority for a product to be labeled as an audio solder. SS-47" is the result of numerous listening tests of prototype models with various mixing ratios.
