Luxman JPR-15000
The JPR-15000 is a cable, not electronics. It is Luxman's flagship RCA interconnect, sold in 1.3m pairs as part of the company's 15000 series line cables. It sat at the top of Luxman's cable range, and period marketing called it "Ultimate flagship line cables (Pin-code type)."
The engineering story is conductor purity. The core wire is 7N-Class D.U.C.C. - 99.99998% pure copper - in a large-diameter configuration meant to keep impedance low. The hot and cold transmission lines are shielded individually in a non-twisted structure. The RCA connectors were newly developed for easy, highly conductive termination. Luxman's own material said the 15000 series was engineered to optimize the technologies the company developed through decades of amplifier design. One UK dealer, Dedicated Audio, summed up the sonic intent this way: the cable "reveals subtle detail while still providing rich, detailed and highly-resolved sound."
A phono variant, the JPR-15000PH, exists at 1.5m with a 5-pin termination. A separate model, the JPC-15000, was fitted with Neutrik XLR connectors. How that model relates to XLR versions of the JPR-15000 is not clearly documented.
The record on this model is thin. No production years are documented. No electrical specs (capacitance, resistance, shielding values) survive in the sources. No collector market data exists beyond retail pricing. What is known, in brief:
- RCA interconnect, 1.3m pair (phono variant 1.5m)
- 7N-Class D.U.C.C. copper conductor, 99.99998% purity
- Large-diameter core, low-impedance design
- Individually shielded hot/cold lines, non-twisted structure
- Original retail around €1,000; seen used at $650
One online listing categorizes the JPR-15000 as an "audio amplifier." It is not. It is an interconnect cable.
