Every Oyaide product is totally made in Japan, even down to minute component. To maintain a high standard of quality and reliability, it is essential to have every production system under their direct and strict control. Oyaide products are designed for special markets where minute vibration from loose connection or due to imperfect choice of materials could become a vital failure. Oyaide carefully designs each and every component for easiness in assembling, simplicity and safety. They carefully select materials for superior sound quality, durability and reliability. Given those requirements, cost factor is secondary while ignoring excess decoration and unnecessary complexity. Oyaide is proud to present a true value for your money and enjoyment.

The basic material for Oyaide connectors is deoxidized Phosphorus Bronze (1.4mm thick) for strength and secure contact. When connected, they can take over a 7kg (15.43 lbs) load. The surface is thoroughly polished not once- but TWICE.

Pull strength of the blade where the cable is terminated is over 30kg (66 lbs)... a result of considering the safety issues.

Plating

In order to improve the sound quality the plating is a very important issue. Therefore our contacts are free of any nickel plating. Instead, we hand polish the metal parts twice. Only by means of this costly process can we achieve a mirror- like surface, and a proper base for the final gold or rhodium plating. This mirror- like finish is a prerequisite for producing clear and vivid sound.

For the Oyaide C-037 model, the plating is super thick (1.5 micron) Silver plating is applied directly on the polished surface of the receptacle and blade and is then polished twice again. A final plating of Rhodium (0.3 micron) is applied and polished twice again.

A combination of the metals chosen, precisely determined thicknesses of each layer and and the polishing process determine the overall sonic quality of the C-037e.
