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.
