Enormous benefits can be gained by installing individual Guardian units on each mains circuit or room of the house. This quietens down the overall electromagnetic environment within the home providing cumulatively beneficial effects for not only your audio and visual systems but your general health and wellbeing too!
Research from many respected authorities indicates that the “Dirty Electricity” that is carried in our normal household supply can be debilitating and very harmful to our health. Installing Guardian protective filters around the home greatly reduces the interferences that generate “Dirty Electricity” radiation in our home and family environment.

CAD Ethernet Control
CAD USB Control
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.
