CAD GC1 Ground control unit - Ex Demo

CAD believes that one of the key reasons so many digital audio products “sound digital” is due to high frequency noise. From the very beginning of CAD we have worked hard to reduce unwanted noise in all our products. Materials and technologies that are used in our 1543 MKII DAC , USB Cables and CAT are included in the GC1 and GC3 Ground Controls.  Over the past 10+ years the amount of high frequency noise on our Mains power has increased dramatically due to the use of computers, routers, modems, wifi, switch mode power supplies, etc.  The high frequency noise that is generated within our audio systems has also increased:  DACs, Servers, Computers, NAS drives, Routers, WiFi, etc. are all connected directly to our audio systems.

The Ground Control contains a mixture of materials that converts high frequency energy into heat.  Our research has found that to achieve the best sound quality the GC1 & GC3 needed to be effective over a large frequency range. This was not easy to accomplish!  The CAD Ground Controls will substantially reduce noise from very high KHz range up to over 10 GHz.
