OYAIDE SGBN banana plug set (4 pcs)

Oyaide SGBN Gold Plated Banana Plugs (SET OF 4)

The new banana plug combines the advantages of both gold-plated and silver-plated plugs, which have never been available before, with durability.

The development of "SGBN" started two years ago with the cooperation of a plating factory to find a new plating combination suitable for speaker terminal connection plugs, while maintaining the simple, well-honed design, meticulous detailing, and non-magnetic phosphor bronze material. The development of "SGBN" started two years ago in cooperation with a plating factory to find a new plating combination suitable for speaker terminal connection plugs. Based on thick-wall 24K gold plating, we produced more than 10 prototypes with different combinations of plating materials and thicknesses of each plating. After repeated comparative listening tests, we selected pure silver + thick-wall 24K gold plating, which gave the best results in terms of both sound quality and durability, and exquisitely tuned it by applying silver plating on the base to extend the high frequency range, while taking advantage of the long-term stability and the good phase characteristics of the mid-range range that gold plating gives. We have upgraded the product.

For the tip diameter, the size was selected based on the standard WBT speaker terminals. Of course, we have also verified it with speaker terminals other than WBT, and it can be adapted to general banana plug receptacle terminals as well. In order to securely clamp the cable conductor, a highly rigid stainless steel set screw with a diameter of 5 mm is used in relation to the cable insertion diameter (4 mm). This ensures a perfect connection by maximizing the contact area without allowing the twisted wire portion of the cable conductor to escape.

The main body is carefully buffed and polished one by one by hand to a mirror finish. The perfectly polished body is plated twice with sterling silver and thick-wall 24K gold plating, which together with the blue screws give the "SGBN" a high-grade, elegant appearance.
