Overview

Level 6.3 Digital RCA Interconnect is our reference design for SPDIF signal transfer. Built with ACElectrum™ silver/gold alloy conductors, ABSOLUTE-Harmony RCA connectors by Keith Louis Eichmann, and a precision-controlled .3 topology, it is engineered to preserve timing accuracy and signal integrity from source to DAC.

Each cable is hand-built in Lake Elmo, Minnesota.

Why ANTICABLES

• ABSOLUTE-Harmony RCA Connectors
  Keith Louis Eichmann’s reference low-mass RCA design, optimized for contact purity and continuity.
• ACElectrum™ Silver/Gold Conductors
  Combines the resolving power of silver with the tonal stability and balance of gold.
• Precision .3 Topology
  Maintains true 75-ohm characteristic impedance end-to-end for stable transmission and reduced jitter.
• Air-Dielectric Architecture
  Conductors are suspended in free air with minimal coating to reduce stored energy and distortion.
• Built by Hand
  Each cable is individually assembled, verified, and finished for consistency and longevity.

For Reference Digital Systems

Level 6.3 Digital RCA Interconnect is designed for SPDIF connections between transports, streamers, and DACs where timing accuracy and noise control are critical. The design prioritizes signal stability and coherence over complexity or mass.

Optional burn-in and cryogenic treatments are available.
