Core Line – Interconnect (RCA Pair)

Prosper Cables – Core Line – Line-Level Interface (RCA Pair)

Refined Signal Geometry

The Core Line Line-Level Interface is designed for stable signal transfer in short-to-moderate run applications including preamp connections, DAC outputs, subwoofer routing and phono stage integration.

Positioned within the Prosper Cables Core Line, this configuration introduces a more refined and flexible signal platform built around professional-grade Mogami cable architecture. Compared to the Classic Line, the Core Line offers improved flexibility, easier routing and expanded connector options while maintaining the controlled execution and long-term reliability central to Prosper Cables builds.

This configuration is optimized for installations where clean signal transfer, cable flexibility and connector compatibility are priorities.

Each pair is hand-built in Prosper, Texas. Conductors are prepared, soldered, strain-managed and fully inspected prior to shipment.

Core Line emphasizes:

• Refined signal geometry
• Stable shielding and noise management
• Improved cable flexibility
• Expanded termination options
• Precision termination integrity
• Durable long-term construction

RCA Connector Options

Switchcraft Gold-Plated RCA (Standard)

The default connector option for the Core Line.

Designed in the USA, these compact connectors are reliable, durable and especially well suited for vintage equipment, tightly spaced inputs and real-world system installations where larger connectors can become cumbersome.

KLE Bullet-Style RCA (PICTURED)

One of my personal favorite connector designs.

Designed in Australia, KLE connectors use a lightweight, low-mass approach that minimizes excess metal in the signal path. Their lightweight construction and elegant design make them an excellent option for customers seeking a more minimalist connector platform.

WBT Silver-Plated Locking RCA ($$$)

Available for customers who specifically want locking RCA connectors.

Designed in Germany, these connectors provide an extremely secure mechanical fit once locked into place. Because of the locking mechanism, they can be more difficult to install or remove in tight spaces, but for systems where maximum connector retention is desired, they fit the bill.

Connector selection affects final pricing and will be reflected in the selectable options above.

Available in standard lengths with custom configurations upon request.

All cables are built to order.
