The 7NSP-Shupreme X is Zonotone’s current flagship speaker cable — the successor to the original Shupreme, built for listeners who want everything the company knows about conductor metallurgy in one design. Five carefully selected materials — ultrapure 7NCu (99.99999% copper), a high-purity copper alloy, PCUHD, silver-plated OFC and OFC — are hybridised in different diameters to Zonotone’s proprietary golden ratio, then laid up in the company’s DMHC multi-core structure with fully independent, individually insulated cores. The aggregate conductor is a massive 9.5sq (8-core) per polarity in single-wire configuration. The presentation is dense, rich and effortlessly authoritative — a cable for reference-grade systems. Hand-terminated in our workshop with Zonotone’s own 10-series LUG connectors, with bi-wire and matching cable-boot options available.
