HiDiamond PERFORMANCE GOLD Speaker 
 
HiDiamond High-End Speaker Cable with UP-4VRC© Copper, Graphite Shielding, XLPE Insulation, and Rhodium-Plated Connectors
 
This ultra-high-end speaker cable employs HiDiamond’s proprietary UP-4VRC© (Ultra Pure Single Crystal Copper) technology—an advanced evolution beyond the Bronze 4VRC© (SCC 4VRC) series—resulting in notably lower inductance, capacitance, and resistance, ensuring superbly transparent signal transmission.
 
Uniquely, this model integrates graphite within the conductor assembly to effectively block internally generated electromagnetic interference (EMI) caused by the passage of electrical signals. The graphite shielding guarantees that the musical signal remains pristine and uncontaminated by noise, significantly enhancing clarity and detail.
 
The cable features an advanced XLPE (Cross-Linked Polyethylene) insulation, claimed by HiDiamond to be 100 times more effective than standard Teflon. This insulation technology reduces transient spikes, thereby narrowing the electrical barrier surrounding the signal path. The resulting performance is characterized by exceptional waveform linearity, reduced sinusoidal distortion, and unparalleled naturalness and musical realism.
 
Internally, the cable utilizes a sophisticated twisted conductor geometry with 8 × 2.5 mm² conductors, designed explicitly to achieve a balanced and coherent sound signature across the entire audible frequency spectrum, complemented by powerful, controlled bass extension.
 
The cable is completed by premium termination options:
 
Proprietary Rhodium-plated banana plugs, enclosed in NFC-treated carbon fiber housings, offering optimal conductivity, mechanical stability, and vibrational damping.
Optional very thick Rhodium-plated spade connectors (forks) available upon request, for superior contact quality in high-performance systems.
 
This model is specifically aimed at audiophiles and industry professionals who demand uncompromising sonic accuracy, dynamic clarity, and noise-free performance at the highest level.
