Core 4D RCA

Core 4D RCA

The Core 4D is a top-category representative of the Core series RCA interconnect cables, designed for the high-end category of audio systems.

Core 4D RCA interconnect cable

  • Ultra-clear, precise and natural sound
  • Full frequency-range extension
  • Natural mid-range and tight bass
  • Wide and deep holographic sound-stage
  • Realistic sound and expansive spatial pure details
  • Extensive and powerful dynamics
  • Ultra-extremely low noise


The Core 4D RCA interconnect cable features balanced quad Mono-core helix conductors, full-separate multi-purpose conductors, reduced resistance, and virtual grounding technology. The appearance of the Core 4D model has the newest 4D braid structure, which ensures full-symmetrical transverse positioning, thereby minimizing the inductive and capacitive effects of the parallel construction of the conductors, which negatively affects the phase accuracy of the signal.

The balanced quad Mono-core helix-structured conductors are coated with a special antistatic film, synthetic polymer insulation, and a special high-density polyester damping outer casing. The dielectric constant of the high-density polyester layer is lower than that of commonly used Teflon insulation and provides adequate protection against environmental vibrations.

The new dual Nano Black Helix outer layer not only gives the Core 4D RCA interconnect cable a special and unique look, but the special metallised polymer film coated with a 500-nanometer-thick metal layer prevents radio frequencies and electromagnetic interference from entering the cable’s internal structure. Similar metallised polymer films are used in NASA spacesuits to reflect radiation and it has been applied as an antistatic layer for insulating materials in aircraft.

In pure copper wires, the fields generated by the current are effectively attenuated by internal separation, while the new, improved nano Black Helix layer is responsible for external electromagnetic and radio frequency noise protection, which together reduces the negative interaction between current in the conductor and insulation.

Virtual Grounding technology

The Core 4D RCA interconnect cable with Virtual Grounding technology provides extremely efficient noise-free signal transmission. The ever-expanding wireless technologies, electromagnetic noise, and magnetic fields generated by home appliances and other electronics cause stray voltages that negatively affect signal clarity and sound reproduction. The Virtual Grounding technology of the Core 4D RCA interconnect cable provides an independent virtual ground point that can effectively dissipate radio frequency / electromagnetic noise, ensuring signal clarity. The result is realistic sound, expansive spatial details, greater dynamics, and an expansive sound stage.


The Core 4D RCA model has high-quality, locking, selected, pure silver-plated high-purity copper connectors. The pure silver coating on the outside of the contacts provides a proper connection that has measurably better electrical parameters and clearer signal transmission than the gold coating.

The Core 4D RCA interconnect is placed in a special tissue bag after the last quality check.
