CAD believes one of the key reasons so many digital audio products “sound digital” is due to high frequency noise generated by the microprocessors inside. The Ground Control contains a mixture of materials that converts high frequency energy into heat. Their research has found to achieve the best sound quality the GC1, GC3 & GC-R needed to be effective over a large frequency range.
The CAD GC1, GC3 & GC-R Ground Controls can be connected to any audio product that has an unused output or input connection. If your DAC, streamer, computer, phone stage, preamplifier, amplifier, CD Player, NAS, etc. has a spare output/input connector like an RCA, XLR, Spade, USB or BNC you can connect the Ground Control to that. We supply a range of interconnects with various connectors. The other end of the connector has a single 4mm banana plug that attaches to the Ground Control.
The results are astounding. The CAD will help reveal the details that have been hiding in your system!
