Oyaide SGBN Banana Plug Set of four Pure Silver Thick-wall 24K gold Plated Japan
OYAIDE SGBN Banana Plug (set of 4). 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 without any habit of gold plating. The upgrade has been achieved. 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.

SGBN aimed to complete this theme with only the characteristics of the material. Phosphor bronze was used to achieve a secure hold with a minimum number of parts. Phosphor bronze is widely used for contacts, which are the key components of electrical products, because of its excellent springiness and electrical characteristics. In planning SGBN, the most careful attention was paid to the contact area around the tip. In order to secure the maximum contact area, the tip is divided into four sections with cross slits, and the slits are designed to fit closely together when inserted. The tip length is designed to perfectly match WBT's speaker terminals. We created more than a dozen samples in increments of 30µm from the standard value of 3.8mm, and selected the size and shape that could be said to be the smoothest and tightest. In addition, we have also tested speaker terminals other than those made by WBT, and they can be used with any type of banana plug receptacle terminals. The cable insertion part, which is set for a maximum cable diameter of 4 mm 5.5 sq. , is tapered to facilitate insertion of twisted wires into the main body. Dual screw clamp method is used for connection. The cable and main body are securely contacted and fixed with two screws. In addition, the screw part for fixing the cable also shows particular attention to detail. A highly rigid stainless steel set screw with a diameter of 5mm is used for the 4mm-diameter cable penetration area. This eliminates the gap between the main body and the screw and maximizes the contact area.

The "SGBN" was created with outstanding machining precision: an 8 mm round phosphor bronze bar was machined with high precision using a highly programmed CNC machining system. The machined body is mechanically barrel polished, then buffed and polished one by one by hand to a smooth mirror finish. The mirror-finished body is then plated with sterling silver as the base coat, followed by thick-wall 24K gold plating. In general, gold plating has a straightforward characteristic with no habit from low to mid-high frequencies, but the extension of the high frequency range may seem a little lacking.

" SGBN" is exquisitely tuned by applying silver plating to the base to extend the high-frequency range, while taking advantage of the long-term stability and the uniquely good phase characteristics of the mid-range range that gold plating provides. In order to confirm the long-term stability of the new plating combination, it has been tested for more than 18 months of continuous use to ensure its reliability. While most gold-plated terminals use magnetic electro-nickel plating as an undercoat to prevent erosion, the gold plating on Oyaide products eliminates electro-nickel, thereby preventing sound quality degradation. Mirror finish and direct plating. It is simple, which is why it must be crafted.

Oyaide's philosophy and craftsmanship are condensed here as well. Proud to be "Made in Japan SGBN" is a proof of highly polished Japanese craftsmanship. New sterling silver plating base + thick 24k gold plating finish.

The silver plating is exquisitely tuned to extend the high frequency range while taking advantage of the long-term stability and non-habitual mid-range phase characteristics provided by the gold plating. The WBT speaker terminal was selected as the standard size, and after more than a dozen cut-and-tries of 30 microns each, a sweet spot was selected that allows easy insertion and does not come off easily. In order to demonstrate the excellent springiness of phosphor bronze, a cross slit was made at the insertion point of the tip to improve the adhesiveness to the terminal.

A 5mm-diameter high-rigidity blue stainless steel set screw is used for the 4mm-diameter cable feed-through. This eliminates the gap between the body and the screw, and the cable and body make secure contact and are secured by the two screws. The 8mm-diameter phosphor bronze round bar is CNC-machined to a high degree of precision. After mechanical barrel polishing, each piece is buffed by hand for a mirror finish.

Material: Phosphor bronze (RoHS compliant). Plating: Pure silver plating base + thick 24K gold plating. Cable connection method: Dual screw clamp method. Applicable cable diameter: up to 4.0mm (5.5sq).
