The story
Grounding differences between components lead to noise and hum; a central grounding point removes them, and Cardas says the result is greater dynamics, better spatial imaging and a lower noise floor, especially where there is a lot of radio-frequency and electromagnetic interference. The Cardas Ground Cable is a single 17.5 AWG Grade 1 copper Litz conductor with Golden Ratio stranding in a clear PVC jacket.
One end connects to the ground point — a Cardas CAB banana in the 4 mm jack of a Nautilus Power Strip (several ground cables can stack on one CAB), or a spade or banana on another maker's ground box — and the other to an unused line-level RCA or XLR input on a component, or to a chassis ground point with a spade. Every system is different, so Cardas builds any length with nearly any connector.
Pick the equipment end by what is free on the component: an unused RCA or XLR input, or a spade for a chassis ground post. For a Nautilus Power Strip as the central ground, use a banana at the ground end and add a Cardas CAB banana (sold separately) to the 4 mm jack; one banana and up to three spades can stack on it. Cardas Ground Cables also work with other makers' ground boxes that take spades or bananas.
