The QED Reference Custom Made Digital Coaxial Audio Cable is ideal for use in your home cinema and hi-fi setup. QED Reference Digital Audio 40 is the new standard for digital coaxial S/PDIF signals benefiting from over 40 years of award-winning expertise. It utilises a carefully engineered geometry to achieve the precise characteristic impedance required for the maximum transfer of S/PDIF signals. Silver-plated conductors deliver a low resistance path for high frequencies and QED Digiloc plugs more closely match the cables characteristic impedance reducing return loss by up to 1dB when compared to conventional RCA plugs. The cable comes fitted with QED Reference Digital Audio 40 Coaxial Plug ensuring optimal signal integrity. Please Note: This cable comes pre-built images are for reference only.
