CAD Ground Cable

Computer Audio Design · Ground Control Dedicated Ground Cable · Reduces High-Frequency Noise

The CAD Ground Cable is a dedicated ground cable designed by Computer Audio Design (CAD) specifically for its Ground Control grounding devices (GC1.1, GC3.1, GC-R). By connecting the signal ground of audio equipment to a Ground Control unit, it effectively absorbs and converts high-frequency noise into thermal energy, significantly lowering the system's noise floor and enhancing sound clarity, dynamics, and realism.

Suitable for a variety of high-end audio systems, especially digital sources, DACs, preamplifiers, and other equipment.

Sound Performance and Enhancement

When using the CAD Ground Cable with Ground Control, the system gains the following improvements:

• Blacker, quieter background, significantly reduced noise floor
• Tighter, deeper bass with clearer layering and definition
• More precise rhythm, transient attack, and decay (PRAT)
• Wider, deeper soundstage
• More natural and realistic vocals and instruments
• Improved detail resolution, leading to a more immersive and satisfying overall musical experience

Especially suitable for connecting digital sources (servers, DACs, streamers) and preamplifier or amplifier input terminals, helping the system unleash more musical details.
