The CAD GC3.1 Ground Control is a passive high-frequency noise reduction system designed to improve audio system performance by converting high-frequency energy into heat. It works by connecting to audio component outputs or Earth ground connections, requiring specialized, low-impedance cables to effectively absorb noise from approximately 700kHz up to over 10GHz. The GC3.1 is a more powerful version for the main power earth and chassis, offering substantial noise reduction.

CAD USB Control

£675.00
The new CAD USB Control design resulted from our research and development of the CAD Ground Controls, 1543 MKII DAC and the many USB cables we have produced over the last 10 years. In our experience, reducing unwanted high frequency noise in audio systems significantly improves sound quality. The frequency of noise varies in every audio system and in each domestic environment – even the time of day on mains power. The USB Control reduces this unwanted high frequency noise across an extremely broad frequency spectrum, from KHz up into the GHz range. HiFi + Review
