HiDiamond Interconnect Cable with UP-4VRC© Copper, XLPE Insulation, and Silver WBT Connectors
 
This premium-grade interconnect cable is constructed using HiDiamond’s UP-4VRC© (Ultra Pure Single Crystal Copper) conductors — a significant technological advancement over the earlier Bronze 4VRC© (SCC 4VRC) series. The UP-SCC 4VRC refinement process yields lower inductance, capacitance, and resistance, enabling highly efficient and transparent signal transmission, especially critical in interconnect applications.
 
The conductors are insulated with XLPE (Cross-Linked Polyethylene), a high-performance dielectric that HiDiamond asserts is 100 times more effective than standard Teflon. This reduces signal distortion by lowering the spike release threshold and minimizing the width of the signal barrier. The result is greater signal linearity, reduced amplitude distortion, and an improved sense of natural musical flow.
 
For terminations, this model is equipped with Silver WBT connectors, renowned for their precision machining, ultra-low contact resistance, and excellent long-term durability. These connectors enhance the signal path and ensure the cable maintains high performance over time, even under repeated connection cycles.
 
This cable is a superb choice for audiophiles seeking a clean, coherent, and dynamically expressive signal path, especially in high-end analog or digital source applications.
