Oyaide SGSL Silver/Gold plated spades
The SGSL, a non-magnetic speaker Y-lug made in Japan from lead-free, iron-free brass and compliant with RoHS requirements. Its stepped 6mm and 8mm fork opening provides compatibility with a wide range of speaker terminals.
The body is formed from a 15mm brass bar using dedicated tooling, then CNC-machined and heat-treated to relieve manufacturing stress. It is barrel-polished and hand-buffed to a mirror finish before receiving a silver underplate and thick 24K gold outer plating. No magnetic nickel undercoat is used.
The tapered cable entry accepts conductors up to 4mm in diameter, approximately 5.5mm². Two rigid 5 mm stainless-steel set screws clamp the conductor securely, maximising the contact area and preventing individual strands from escaping.
Plating
The mirror-finished body is plated with sterling silver as the base coat and then finished with thick-walled 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." SGSL" 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 uncluttered mid-range phase characteristics provided by gold plating.
In order to confirm the 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.
