HiDiamond TOP SILVER Speaker 
 
HiDiamond High-End Speaker Cable with UP-4VRC© Copper, XLPE Insulation, and Carbon Fiber NFC Housing
 
This top-tier speaker cable is built with HiDiamond’s UP-4VRC© (Ultra Pure Single Crystal Copper) technology, an evolution beyond the Bronze 4VRC© (SCC 4VRC) series. Through enhanced copper purity and advanced refinement techniques, this cable delivers even lower inductance, capacitance, and resistance, ensuring exceptional electrical and sonic performance.
 
The conductors are encased in XLPE (Cross-Linked Polyethylene) insulation, which HiDiamond states is 100 times more effective than conventional Teflon in dielectric efficiency. This advanced material significantly reduces the spike release threshold and narrows the signal barrier, yielding greater waveform linearity, lower amplitude distortion, and heightened naturalness in musical reproduction.
 
Compared to the Performance series, this cable uses greater quantities of copper and internal filament mass, resulting in improved current delivery and tonal stability. Internally, the cable features twisted conductor geometry, a proven design for balanced frequency response and enhanced EMI rejection.
 
With a substantial conductor structure of 6 × 2.5 mm², this cable ensures powerful and precise bass extension, along with:
 
A reinforced mid-bass that adds physicality and impact to low-end reproduction.
Warm, firm vocal presence that maintains clarity and tonal accuracy.
High-frequency reproduction that is precise, transparent, and non-fatiguing.
 
Terminations are executed using custom Rhodium-plated connectors, housed in NFC-treated carbon fiber enclosures, which contribute to superior signal integrity, mechanical stability, and vibrational damping.
 
This model is an ideal choice for reference-level systems, where both technical precision and emotional musicality are paramount.
