ddHiFi RC30A / RC40A / RC30B Cables | Desktop RCA Cables

Premium Shielded Silver RCA Cables for Desktop Systems, Offering Comprehensive Connectivity with All Common Connectors

• Three models of shielded silver RCA cables to meet various connection needs
• Pure Silver, Furukawa Silver-Copper Alloy, and Silver-plated OCC structure
• High-quality shielding for superior and reliable sound clarity

Comprehensive Connectivity

The ddHiFi RC series upgrade cables—RC30A, RC40A, and RC30B—are designed for different connectors to connect desktop decoding systems (3.5mm, 4.4mm*, RCA) to amplifiers or active speakers via RCA inputs. These high-quality cables ensure superior signal transmission and compatibility with common audio devices.

*Please note that the 4.4mm plug of the RC40A is not a balanced structure. In order to make the GND at the end of the RCA end connected, it's required to use the GND of the 4.4mm plug as a loop, with the negative of the left and right channels unconnected.

Double Shielded Coaxial Structure

The RC series features a unique double-shielded coaxial structure, where two signal wires are arranged in a coaxial layout with an additional outer shielding layer. This design includes three layers of conductors and insulation, offering superior tensile strength and delivering a cleaner, noise-free background for signal transmission.

More than Pure Silver

The core conductor is crafted from two types of pure silver with varying diameters, combined with silver-plated OCC and Furukawa silver-copper alloy. With a cross-sectional area of up to 22.8AWG, it ensures high-power transmission while maintaining optimal efficiency across different signal types. This design not only enhances transmission but also improves sound quality, delivering more accurate tonal expression for various instruments and a clearer sense of sound positioning.

RCA Plug Features

High-Purity Gold-Plated Copper
The main core and grounding plate of the RCA plug are made of high-purity copper and the outer layer is electroplated with thick 24K gold, which has excellent conductivity.

Hidden Joint Design
Since the fixation is completed internally, there is no long sleeve at the joint of the cable end. The outer edge is designed to be arc-shaped, which can greatly prevent the outer skin from breakage.

Built-In RCA Plug
The exposed metal parts of a connecting cable can easily oxidize. However, the grounding plate on the RCA plug has a dust-proof protective shell, which can effectively isolate dust.
