QED Reference Digital Audio 40 Interconnect – 0.6m

The QED Reference Digital Audio 40 sets a new benchmark in digital coaxial S/PDIF signal transfer. Its geometry has been precisely engineered to achieve optimal impedance for signal integrity, while the silver-plated conductors provide a low-resistance path for high-frequency signals. QED’s Digiloc2™ RCA plugs enhance the impedance match, reducing return loss by up to 1.5dB for cleaner audio output. With triple-layer electromagnetic shielding, this cable ensures minimal signal jitter and maximum protection from electromagnetic interference. A hollow central pin and a non-conductive, low eddy current plug body further improve high-frequency signal fidelity. Designed for audiophiles, the Reference Digital Audio 40 is built to deliver clearly audible sonic improvements and a richer listening experience. It comes with a lifetime guarantee and features top-tier materials like 99.999% OFC copper and low permittivity foamed polyethylene dielectric. Ideal for connecting digital audio sources like CD or Blu-ray players to high-end audio systems, this cable exemplifies cutting-edge performance and durability.
