The Oyaide Advantage
Oyaide defines a new standard of excellence...
While other manufacturers reworked existing AC connector and receptacle designs to adapt them for audio, Oyaide engineers (whose knowledge of physics and materials with regard to sound is second to none) set out to examine each material employed in exhaustive detail to determine what would yield the best result. Oyaide determined their connectors would have to be designed and built �from the ground up�. In the process, Oyaide has defined a new standard of excellence.
What are the most important considerations for a secure AC electrical connection?
1.) Appropriate Hardness: The contact material must maintain its
exact shape over time without any adverse effect to the sound
2.) Appropriate Springiness: The material should have the ability to rebound from the compression of first contact and expand to make firm long-term contact. This is highly important as a superior contact has the ability to eliminate vibration
due to the movement of electrons (current) or electromagnetic fields (signal) through the contacts. For clean transport,
secure contacts are crucial.
4.) Appropriate Choice of plating materials: The type of materials, their combinations and thickness must be carefully chosen
5.) Surface finish: At a microscopic level, where metal meets metal, the more flat and uniform the final finish, the greater the level of contact. Oyaide insists on strict control of surface quality, including uniformity of plating thickness for cleaner sound quality.

How do Oyaide connectors differ from typical �Audio Grade�
Oyaide connectors use Deoxidized Phosphor Bronze as a base
material, which meets the first three criteria listed above
almost perfectly (appropriate hardness, springiness and conductivity).
Typical �audio grade� connectors use brass, which is weak,
lacks springiness and is generally not pure, containing significant
amounts of iron and lead. Copper, while having superior conductivity
to brass, lacks appropriate hardness and springiness.
2.) Oyaide did exhaustive research not only into which plating
materials would be optimal, but also into which combinations
and what thickness would yield the best result. Typical plating
methods do not meet the laboratory grade standard necessary
to achieve the best contact. All Oyaide products are plated
using the highly precise hard contact plating method, which
must be performed in Oyaide's state of the art facility. The
use of nickel, which degrades the sound, is avoided. The three
equally valid and accurate combinations arrived at are:
The contacts of Oyaide connectors are polished twice before
plating and twice again after each plating process. This attention
to detail is unrivalled. Even a cursory examination of a typical
�audiophile grade� connector will reveal a rough surface.
By comparison, the Oyaide connector is polished to a jewelry
quality finish, not for looks, though that is a desirable
side benefit, but for best connectivity and therefore best
sound. ( See point 5 above)
