The SPSL is a sophisticated spade lug that combines elegance with high performance. After extensive listening tests, we chose RoHS-compliant pure brass for the base and applied silver and platinum plating. The main body is precision CNC-machined from a 15mm phosphor bronze bar, then meticulously hand-polished.
A strong 5mm stainless steel screw secures the 4mm cable penetration, filling the gap between the body and screw. The blue quench-hardened screws enhance both durability and aesthetics.

Dual - screw locking system
The dual-screw rocking system, along with SRBN, ensures a secure connection. This setup effectively fills internal space and holds the conductor in place, while the blue screws emphasize the SPSL's beauty.

Precision machining
Crafted entirely from pure Japanese brass, the body undergoes precision machining and a thorough low-temperature annealing process, followed by mechanical barreling and hand polishing for a refined finish.
