HiDiamond TOP EXCLUSIVE Signal D10 
 
HiDiamond D10 Reference RCA Cable with ULTRA-PURE OFC UP-4VRC© Copper and Silver WBT Nextgen Connectors
 
The HiDiamond D10 represents the pinnacle of analog interconnect design, built upon the latest refinement of HiDiamond’s exclusive UP-4VRC© (Ultra Pure Single Crystal Copper) technology. Now processed to a new standard and referred to as ULTRA-PURE OXYGEN FREE 4VRC©, this conductor material sets a new benchmark for signal purity, tonal accuracy, and dynamic realism.
 
The D10 distinguishes itself with a dual-path signal architecture, incorporating two different types of internal signal cable specifically selected to achieve ultra-clean, spatially defined, and dynamically articulate analog audio reproduction. This advanced internal topology maximizes instrumental separation, resolution, and stereo depth, raising the bar for RCA cable performance.
 
Shielding is further optimized with graphite integration and precise conductor geometry to reject noise and preserve low-level detail. Combined with XLPE dielectric insulation — rated by HiDiamond as 100× more effective than Teflon — the D10 ensures:
 
Tightly controlled signal propagation
Lower peak distortion and noise floor
A natural and immersive sonic presentation
 
The cable is terminated with Silver WBT Nextgen connectors, providing:
 
Exceptional conductivity
Extremely low contact resistance
Superior mechanical and signal integrity
 
This is not merely an RCA cable — it is a reference-grade analog signal conduit, ideal for elite-level two-channel systems and high-fidelity signal chains where transparency, spatial realism, and musical precision are required without compromise.
