Luxman JPS-15000/2 (2025)
Documentation on the Luxman JPS-15000/2 is thin. What exists comes almost entirely from retail listings, not reviews or archival material. This much is clear: it is Luxman's current flagship speaker cable, part of the company's 15000 series reference line, and the "/2" marks the 2.0-meter length.
The cable is built around a large-diameter core of high-purity 7N-class D.U.C.C. (Dia Ultra Crystallized Copper), which is 99.99998% pure copper, chosen to keep impedance low. A drain wire of oxygen-free copper (φ0.08mm × 30 strands) is also specified. Luxman's own marketing says the 15000 series is engineered to optimize the technologies and know-how gained from decades of amplifier development. Retailers echo that language and describe the sound as revealing subtle detail while staying rich and resolved. One community discussion of the JPS-15000 noted that the conductor has no silver and no silver plating. It is pure copper throughout. The cable is also sold in a 3.0m version. A sibling phono cable, the JPC-15000PH (5-pin DIN to XLR, 1.5m), shares the 15000 series designation.
Retail pricing has been listed around £2,800 (for the 3M version), €3,000, or roughly ¥275,000. At least one dealer quoted price on request. The only dated listing found claims a 2025 manufacturing year, and the cable is sold as brand new, not as vintage stock. So this is a current flagship, not a relic. No formal professional reviews, no measured electrical data beyond the conductor notes above, and no long-term reliability information have surfaced in the available record.
