Viard Audio Design Silver HD20 S/PDIF
75 ohm digital coaxial cable in S/PDIF format, copper-silver conductors and gold-plated RCA connectors, designed for demanding digital links between source and converter.
Description
The Silver HD20 is a 75 ohm digital coaxial cable compliant with the S/PDIF standard, designed to connect a digital source to a converter or amplifier fitted with a coaxial input. It belongs to the category of high-end cables intended to optimise digital signal transmission between two hi-fi components.
The centre conductor and the insulating braid are made of copper and silver, a choice of materials aimed at limiting signal losses on the digital link. The RCA connectors feature gold-plated contacts, a treatment that promotes stable electrical contact and limits oxidation over time. The dielectric is made of Teflon (PTFE), an insulating material recognised for its stability. The outer sheath, in white silicone with a 12 mm diameter, provides good mechanical compliance to the cable while resisting UV and chemical agents, allowing for intensive use or frequent handling.
This cable is aimed at users wishing to take care over the digital link between a player, a transport or a network source and a DAC or an amplifier incorporating a converter, within a system where the attention paid to peripherals already reflects a certain level of sonic expectation.

What to check before buying used
The white silicone sheath shows creasing and handling marks more visibly than a dark sheath: check for the absence of cracks or pronounced kinks along the entire length. Check that the gold-plated RCA connectors hold securely in the sockets, as play or an uncertain contact can cause dropouts or interference on the digital stream. A connection test with the source and converter remains the best way to confirm the integrity of the shielding and centre conductor.
