Classic Line – Interconnect (RCA Pair)

**Prior to May 2026, this was the Core Line offering. 

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

Extended Architecture (Just a heavier shielded version of the class). These aren't as flexible, and are better for longer lengths. 

Refined Signal Geometry for Long-Distance Stability

The Extended Architecture configuration is optimized for longer cable runs and subwoofer integration where maintaining stable impedance and low-noise performance over distance becomes more critical.

This is my preferred configuration for subwoofer connections and installations exceeding typical rack-to-rack spacing.
Positioned within the Prosper Cables Classic Line, Extended Architecture utilizes increased conductor mass and a larger sleeving profile to maintain structural stability and shielding integrity across longer runs.

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

Extended Architecture emphasizes:
• Stable impedance behavior over longer distances
• Increased conductor mass for extended runs
• Subwoofer-focused system integration
• Durable large-profile construction

Built to order.
