Oyaide [Autumn Super Sale] DR-510 [0.7m] (1 piece)

★Unrelenting purity. The ultimate pure silver digital cable, made from the finest materials.

The FTVS-510 caused a sensation upon its release. The answer to the question of how to transmit signals without degradation was pure silver. High-quality 5N pure silver is used as the center conductor, boasting a level of conductivity never before achieved with other metals. Furthermore, the FTVS-510 underwent extensive testing, including insulation, EMI, and performance characteristics, to create a cable that fully utilizes the rare metal "pure silver." Its innovative and cutting-edge concept has earned it acclaim not only for video but also as a digital cable. The DR-510/DB-510, with its coordinated terminals, also serves as a spokesperson for Oyaide Electric's pursuit of purity. The terminals feature SLSC/SLSB pure silver contacts for flawless pure silver transmission. The exterior design is an extension of the company's technical design, and the brilliant, lustrous silver-coated mesh symbolizes the true purity sought by the DR-510/DB-510. The DR-510/DB-510 promises an insatiable purity that is difficult to describe in a single word, a genuine emotion that cannot be conveyed in words. The DR-510/DB-510 is a supreme digital cable made from the finest materials. It is imbued with emotion that cannot be expressed in technical data.

The central conductor is made of 5N (99.9995%) pure silver, which has the highest conductivity of any metal. The production process is uncompromising, with continuous casting in a high-frequency electric furnace, 19 cold rolling processes, two annealing processes, drawing using a diamond die, and skin-pass processing. This results in a high-quality silver wire with not only high purity silver but also no gaps in the grain boundaries.

When a signal flows through a semiconductor cable, weak vibrations occur, and these vibrations cause corona discharges in statically charged materials. Therefore, by providing a semiconductor layer around the outer periphery of the insulating layer, static electricity can be released without affecting the conductor.
■Insulator: The insulator is made of PFA, which has the lowest dielectric constant of all insulating materials. Furthermore, a composite structure with FPE (foamed polyethylene) is used for the purpose of vibration diffusion. This ensures not only excellent electrical properties but also vibration prevention.

■Exterior The exterior is made of a simple reinforced fiber sleeve, without any coloring of the material, and has been treated with an anti-static coating to prevent static electricity from building up due to friction, etc.

■Two-layer shielding: In order to strengthen against low-frequency noise, copper tape and tin-plated copper braid are combined, but the ``FTVS-510'' is further strengthened against high-frequency noise by using silver-plated copper braid (95%) with high frequency characteristics.

■ Connectors with Pure Silver Center Pins At Oyaide Electric, we consider the terminal plug to be a component of the cable. It goes without saying that we must increase the conductivity of the cable, but if the contacts in the plug also do not, then it cannot be called truly exclusive. By adopting the pure silver contact connectors SLSC/SLSB, we have achieved flawless pure silver transmission.

■Uses SS-47 solder, which is specifically designed for audio equipment.
The wiring is soldered using Oyaide Electric's original SS-47 solder, specifically for audio equipment. Standard solders typically have a tin purity of around 99.9% (3N) due to cost considerations. SS-47 further increases purity, eliminating impurities to the utmost, resulting in a high-purity tin of over 99.993% (4N). Silver and copper are also blended to improve conductivity and prevent solder erosion. While standard alloy solders typically contain 3-3.5% silver, SS-47 generously uses a whopping 4.7%. Furthermore, 1.7% copper, the metal with the second highest conductivity after silver, is blended. This blending ratio dramatically improves conductivity, successfully achieving a eutectic point of 217°C.
Of course, these blending ratios were not determined solely on the basis of numerical data and workability. We believe that sound quality should be given top priority when labeling a solder as audio solder. SS-47 was created through countless listening tests of prototype models with various blending ratios.
