At kr 1,050 SEK, this Supra HDMI AOC 4K 2.0 20m listing sits just below the 75th percentile (kr 1,157 SEK) of recent comparable SEK asking prices, making it a solid, fair-to-strong deal rather than a bargain, but clearly not ambitious. The median for 20 recent listings is kr 653 SEK, so this price is notably higher than average, yet it remains well within the upper quartile range and reflects the premium nature of this optical HDMI cable for long runs.
This cable is highly regarded in the hi-fi community for its optical fiber conductors that eliminate electromagnetic interference over long distances, delivering pristine 4K/60p, HDR, and HDCP 2.2 performance up to 20m without signal degradation. Its 4.5mm diameter and gold-plated shielded metal connectors add durability, while the 20Gbps bandwidth ensures compatibility with modern high-end AV setups. For a 20m run, this is a rare and worthwhile upgrade, and at this price point, it represents a genuine buying opportunity for enthusiasts needing long, clean HDMI transmission.

Supra Cables emerged from Sweden in 1976, founded by engineer Tommy Jenving, a former Ericsson employee whose vision ignited the global audiophile cable revolution. Based in Ljungskile, the brand—operating under Jenving Technology—prioritized rigorous, measurement-driven design from the outset, producing its first dedicated loudspeaker cables when most enthusiasts relied on basic lighting flex. Jenving's passing in 2011 has not dimmed the company's ethos, which endures through in-house Swedish manufacturing and a steadfast "No-Nonsense Concept" that favors empirical testing over hype.
The brand specializes exclusively in high-quality cables, spanning categories like speaker wires, interconnects, power cords, and digital links including HDMI and DVI. Innovations such as Ply low-inductance speaker cables, tin-plated oxygen-free copper conductors to combat skin effect, square geometry designs, and patented shielded mains technology define their lineup. All products feature pale blue polyethylene sheathing for minimal dielectric absorption, flexibility, and environmental safety, with directional labeling ensuring optimal signal flow.
Supra occupies a respected mid-to-high-end niche among discerning hi-fi buyers, celebrated for Swedish engineering precision and value-driven performance. Awards like "Best in Test" and "Best Buy" underscore its reputation for scientifically verifiable improvements—low inductance, negligible skin effect—without unsubstantiated audible claims. As one of the earliest specialty cable pioneers, it appeals to knowledgeable audiophiles seeking rational, proprietary solutions over boutique extravagance.
