Oyaide DR-510 Digital Cable
RCA terminated digital audio cable
The Oyaide DR-510 is one of the best sounding digital audio cables under $500. If you are looking for a high performance, low cost digital cable, this is it.
The origin of the DR-510
The FTVS-408, a coaxial cable, was designed to be mainly used for digital signal transmission. Although it was meant to be a limited production model, it became a regular product in Oyaide's lineup due to strong to customer demand.
Doing further validation of FTVS-408, Oyaide devoted much energy to providing the finest 5N silver and researching the perfect insulator and shield for the silver conductor. As a result, they produced the FTVS-510 which was designed to be used for antenna, sound and digital signal transmission.
To enhance electrical conductivity of connectors as well as cable, we attached SLSC and SLSB with pure silver contacts for perfect signal transmission by pure silver.
5n Silver conductor
For the core of DR-510, 5N (99.9995%) pure silver is installed. After being melted in a ceramic crucible, it is molded into 15mm diameter round bars. It is further reduced in diameter by means of 19 repetitions of the cold rolling process.
Although the conductor is the most important factor in signal transmission, the insulator is also significant in enhancing the transmitting capabilities of the cable.
For the purpose of lessening signal loss, we employed FEP (Teflon) which provides excellent electrical isolation and low dielectric absorption.
For the first insulation layer, we selected PE (Polyethylene) which keeps permittivity to a minimum and enhances the flexibility of the cable. This layering of these different materials not only enhances the conductor's electric capabilities but also attenuates internal vibration by altering the resonance point.
When signal flows in a cable, it generates ultra small vibrations by which cause the discharge of an electric field. In order to solve this problem, Oyaide installed Carbon PE as a semiconductor layer. By surrounding just the outside of the first insulation layer, its semiconductor layer helps to discharge static buildup from the Teflon layer in an orderly fashion.
The ultra silent background of the DR-510 is provided by a triple-layered shielding structure. The first semiconductor layer attenuates static noise and electric micro waves. The second copper foil shielding protects against high-frequency noise. The third, silver plated mesh shielding, protects against low-frequency noise. It also protects against high-frequency noise by means of the skin effect on the silver plating.
Pure silver termination
The terminal connectors are very important for a cable component. To enhance electrical conductivity of connectors as well as cable, we attached SLSC and SLSB with pure silver contacts for perfect signal transmission.
