RCA Cotton Signature Interconnect Cable, 6N OFC Copper

Natural Sound. Cotton and Copper.

The Pure Line Audio RCA Cotton Signature is a handcrafted copper RCA interconnect cable built around one idea: remove everything that colors the signal. No plastic insulation. No glare. Just high purity metal and natural cotton.

Plastic insulation and coatings can add strained or glaring sonic attributes that feel unnatural to the ear. Cotton does not. The result is a cable that sounds open, natural and rich, with nothing added.

Eight Solid Conductors, Individually Cotton Insulated

Each cable uses eight solid conductors made of OFC 6N pure copper (99.9999% purity). Every conductor has its own cotton insulation, and the conductors are combined in a complex braid. This geometry keeps channels separated, the signal balanced and the capacitance ultra-low, for a presentation that is natural, open and precise.

Built for Silence and Transparency

A braided, grounded shield delivers full EMI/RFI rejection, so the cable stays quiet and transparent even in busy system environments with lots of power supplies and digital gear nearby.

Connectors and Solder That Match the Cable

We terminate with Neotech precision RCA connectors, gold-plated for stable contact and effective shielding. Every solder point uses Mundorf Supreme silver-gold-tin solder with 9.5% silver, chosen for conductivity and long-term resistance to oxidation.

Key Features

  • OFC 6N Solid Copper Conductors: high conductivity, speed and control for natural musical flow.
  • Natural Cotton Dielectric: individual cotton insulation on every conductor, no plastic coloration.
  • Eight-Braid Geometry: channel separation, signal balance and ultra-low capacitance.
  • Superior EMI/RFI Rejection: braided and grounded shield for silence in complex systems.
  • Neotech Precision RCA Connectors: gold-plated for contact stability and tonal purity.
  • Silver-Gold-Tin Solder (9.5% silver): Mundorf Supreme, durable and oxidation resistant.
  • Handcrafted in Europe: built with care and measured for matched impedance performance.

Choose your Interconnect
RCA Interconnects (Single-Ended Systems)

Pure Essence RCA Interconnect
Best for: most home HiFi systems seeking balance and natural flow.

Solid OCC copper conductors deliver tonal neutrality, structural coherence, and long-term listening comfort. An excellent foundation for integrated amplifiers, vinyl systems, and balanced stereo setups. 

Pure Line RCA Cotton Signature
Best for: listeners who want a warm, open and natural presentation.

Eight solid 6N copper conductors, each insulated in natural cotton, deliver a wide soundstage, rich harmonics and precise instrument separation with no coloration. A good match for systems that favour natural tone and harmonic richness over razor-edged detail.

Pure Line Reference Fusion RCA

Best for: high-resolution HiFi systems seeking clarity with harmonic substance.

A hybrid of pure silver and OCC copper that combines transient precision with tonal density. Offers more openness and micro-detail than copper-only designs while maintaining greater body than pure silver alternatives.

Pure Silver RCA Interconnect
Best for: ultra-resolving systems and detail-focused listeners.

Solid OCC silver conductors prioritise speed, micro-detail retrieval, and spatial precision. Ideal for systems that already possess tonal weight and benefit from maximum transparency.

XLR Interconnects (Fully Balanced Systems)

Pure Silver Ribbon Statement XLR
Best for: fully balanced reference systems with nothing left to compromise.

Duelund pure silver ribbon in cotton-oil insulation, spiral-twisted and braided, terminated with Neutrik connectors. Silver speed and micro-detail with tonal weight, for the most resolving balanced systems.

Pure Silver XLR Interconnect

Best for: high-resolution balanced systems seeking maximum transparency.

Solid OCC silver conductors in a balanced architecture preserve phase accuracy, expand soundstage scale, and enhance low-level detail while maintaining low-noise performance.

Pure Line Balanced XLR Interconnect
Best for: balanced systems and longer cable runs requiring stability and interference rejection.

Designed to maintain signal integrity and dynamic consistency across complex balanced signal paths.
