HiDiamond TOP GOLD Digital RCA 
 
HiDiamond Ultra-Pure Interconnect Cable with UP-4VRC© Copper, Graphite Shielding, XLPE Insulation, and Silver WBT Connectors
 
This high-end interconnect cable features HiDiamond’s UP-4VRC© (Ultra Pure Single Crystal Copper) technology, offering enhanced signal performance beyond that of the earlier Bronze 4VRC© (SCC 4VRC) series. Through advanced purification and processing, the UP-SCC 4VRC conductors deliver lower inductance, capacitance, and resistance, enabling faithful signal reproduction with minimal loss.
 
The cable is infused with graphite, an integral shielding element that plays a vital role in blocking electromagnetic noise generated within the cable by the transmission of the electrical signal — the musical signal itself. The result is a noise-free, accurate signal path that preserves the dynamics, nuance, and timbral richness of the original recording.
 
For insulation, HiDiamond uses XLPE (Cross-Linked Polyethylene), which it claims performs 100 times better than traditional Teflon in terms of dielectric behavior. This minimizes high-frequency discharge and electrical signal barrier width, ensuring:
 
Improved waveform stability
Lower harmonic and amplitude distortion
Natural, detailed, and effortless sonic presentation
 
The cable is completed with Silver WBT Nextgen connectors, regarded as a pinnacle in audio terminations for their exceptional conductivity, low contact resistance, and precision mechanical design. These connectors allow the cable to fully disappear sonically, preserving the integrity of the signal without coloration or compression.
 
This model is the ideal choice for audiophile-grade analog or digital interconnects, where extreme neutrality, detail retrieval, and signal cleanliness are required.
