These plugs are not merely high grade. Every possible step has been taken to achieve true "State of the Art". Every one of our products is made under our direct supervision to the highest and strictest standards. Since even minute variations can lead to failure, we carefully choose each part to assure ease of assembly and operation and, especially, safety. Materials are selected for superior sound quality, durability and reliability. To achieve our aim, cost is a secondary consideration. Avoiding unnecessary decoration and complexity, we are proud to deliver these products of value for your listening pleasure.

Pin - Contact Pin

The contact pins are made out of deoxidized phosphorus bronze and machined out of a single piece, for the best possible conductivity.

The feedstock is made out of a bolt 14 mm in diameter that weights 70 grams. The machining has to be done with a highly sophisticated CNC lathe, in order to archive the highest precision on this complex shape.

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 P-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 P-037e.
