Supra Cables

Founded in Sweden in 1976 and still produced in-house in Ljungskile, Supra Cables is built on a “no-nonsense” design philosophy that blends Swedish engineering, real-world performance, and outstanding value. Known particularly for its award-winning Ply speaker cable — a flat braid design with optimised geometry — Supra enhances soundstage, dynamics, and clarity across any system.

At Groove Central, we showcase a range of Supra Cables’ audio and video solutions, from speaker cables and analog RCA / balanced XLR interconnects to digital (USB / HDMI) and power products, including their highly regarded LoRad mains cords and power boards / strips. Each cable is engineered with measurable design goals such as reduced inductance, effective EMI/RFI shielding, and optimised materials to ensure your system performs at its best.

Supra’s lineup includes the entry-to-mid-level Classic Series, the Ply range with its distinctive flat braid geometry for improved soundstage and imaging, the LoRad shielded power cables designed to reduce both electric and magnetic fields, and a selection of video / AV cables such as HDMI 2.1 UHD 8K certified models.

What sets Supra apart is its complete Swedish manufacture, advanced in-house R&D, full batch traceability, and a consistent commitment to genuine “value for money” without compromising performance. Whether you’re upgrading an audiophile hi-fi speaker setup, refining a desktop headphone system, building a home theatre, or improving studio signal clarity, Supra Cables deliver transparency, reduced noise, and long-term reliability.
