Interconnect Cables

Picture
ED 422 Interconnect Cable

The fourth-generation ED 422 interconnect cable sets a new standard for both absolute performance and cost-effectiveness. Slender, flexible, and robust, ED 422 incorporates optimally sized conductors to avoid skin-depth related phase shift within the audio frequency range, insulated with thin-wall Teflon* to minimize undesirable energy storage.

Unshielded ED 422 offers the ultimate potential in terms of openness, dynamic contrast, and natural timbral reproduction, allowing the music to emerge from a deep, silent background.


  • Twisted-Quad geometry
  • Silver-plated Copper conductors
  • Teflon* insulation and inner jacket
  • Abrasion-resistant protective net sleeve
  • Gold-plated Neutrik ProFi RCA, XLR, or TRS connectors
  • Unshielded (for best sound quality) or Shielded configurations

ED 422 Interconnect Cables is available in any custom length, e.g.:

 3 foot pair
ED 422 Interconnect Cable, RCA > RCA       $500.00
 6 foot pair ED 422 Interconnect Cable, RCA > RCA       $740.00
10 foot pair ED 422 Interconnect Cable, RCA > RCA    $1,060.00

ED 422X Unshielded Balanced Interconnect Cable

The ED 422 cable's star-quad geometry offers unsurpassed noise-rejection properties when used in a balanced configuration.

ED 422X adds a discrete external ground wire, enabling unshielded balanced operation for the ulitmate performance in systems with properly executed differential inputs.

  • Twisted-Quad geometry
  • Discrete external ground wire
  • Silver-plated Copper conductors
  • Teflon* insulation and inner jacket
  • Abrasion-resistant protective net sleeve
  • Gold-plated Neutrik XLR or TRS connectors

ED 422X Unshielded Balanced Interconnect Cable is available in any custom length, e.g.

 3 foot pair ED 422X Unshielded Balanced Interconnect Cable, XLR-F > XLR-M       $500.00
 6 foot pair ED 422X Unshielded Balanced Interconnect Cable, XLR-F > XLR-M       $800.00
10 foot pair ED 422X Unshielded Balanced Interconnect Cable, XLR-F > XLR-M    $1,200.00
