QED Reference Digital Audio 40 Cable

QED Reference Digital Audio 40 Cable The new standard for digital coaxial S/PDIF signals. Reference Digital Audio 40 utilizes 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 cable's characteristic  impedance, reducing return loss by up to 1dB when compared to conventional RCA plugs. This ensures optimal signal transfer and improves micro-timing of the audio signal. FEATURES AND BENEFITS Just Listen Silver plated signal carriers, effective high-quality shielding and impedance matched cordage and plugs all combine to create audible sonic improvements when compared to the competition Triple Layer Electromagnetic Shielding By implementing factory-controlled geometry and low permittivity foamed polyethylene dielectrics, Reference Digital Audio 40 maintains the correct characteristic impedance to match the transmission line between digital source and sink precisely. This makes for a very low jitter signal transfer which, listening tests have shown, leads to clearly audible sonic improvements. 75 Ohm Impedance matched Digiloc2TM RCA plugs Feature high-purity copper signal and ground connections supported by a new non-conductive low eddy current body. The hollow central pin eliminates the skin effect at high frequencies and the revised locking barrel design clamps the dual blade ground connection firmly to the RCA sockets for improved noise rejection. The optimised geometry of the plugs and the dielectric materials selected have resulted in a closer impedance match for low jitter S/PDIF transmission, resulting in a measurable 1.5 dB reduction in insertion loss, compared to ordinary RCA plugs The all new Digiloc2™ design cleverly substitutes high rigidity thermoplastic material for both the inner support structure and the cable strain relief to eliminate the distorting effects of eddy currents, which are always present in ordinary plugs where bulk brass is used instead. Triple Layer Electromagnetic Shielding A dual layer closely woven 99.999% OFC shield braid and aluminium mylar wrap with 100% coverage comprise a triple layer electromagnetic shield coaxially spaced around the central signal carrier within a foamed polyethylene dielectric. This ensures that interference signals induced by nearby high current noise sources do not contribute to higher signal jitter than would otherwise be the case. By the same token the shielding prevents unwanted voltage induced interference escaping the cable which might affect nearby analogue signal carriers.
