Oyaide SPSL Platinum/Silver Plated Spades - set of 4
SPSL is state-of-the-art spade lug which creates an aura of elegance. After repeated listening test, we employed RoHS compliant pure brass for the base material and a combination of silver + platinum plating. The main body is trimmed from a phosphor bronze bar of 15mm in diameter by precision CNC machining and is finished by mechanical barreling and hand polishing piece by piece.
The highly-rigid 5mm stainless screw is used for the 4mm cable penetration part. This infills inside space between the body and the screw. The blue screws, made of stainless with quench hardening treatment, are highly-rigid and emphasize the beauty of SPSL.
For its cable connection method, the dual-screw rocking system is employed as well as SRBN.
By employing 5mm dual screw connection system, it infills inside space and holds conductor perfectly. The blue screws, made of stainless with quenching treatment, are highly-rigid and emphasize the beauty of SPSL.
For the body material, we employed pure brass completely made in Japan. The body is trimmed down from 15mm round bar by precision CNC machining and is going through annealing process in low temperature furnace for long time. It is finished by mechanical barreling and hand polishing piece by piece.
