About the QED Signature Audio 40 Interconnect (Pair)
Signature Audio 40 is a fresh design from QED, made to mark 40 years of British-designed cables. The cord is designed first for low capacitance, which QED see as a key factor in a tight sound that keeps the rhythm of the music.
The conductors are silver-plated 99.999% oxygen-free copper with a Teflon dielectric, in an asymmetrical twisted pair with QED’s Complementary Conductor design for high-frequency detail. A silver-plated shield gives full electromagnetic screening, and a Zn/Mn ferrite jacket absorbs noise. The cable is cryogenically treated.
It sits in QED’s Signature range. Use it between a CD player, DAC, turntable phono stage or tuner and an amplifier or AV receiver.
