The groundbreaking Signature Audio 40 analogue audio interconnect celebrates QED’s 40 years at the forefront of British designed audio cables

Signature Audio 40 is an entirely new design concept from QED laboratories. The cordage is designed primarily for low capacitance as this has been identified by QED as a significant factor leading to a high-fidelity experience and makes for a tight sound retaining the rhythm of the original piece. Add our Complementary Conductor Technology™ for high frequency detail and our Analoc2™ technology to maximise signal integrity and the result is what we feel to be the most innovative interconnect ever made by QED. Please see our ‘cables matter’ section below for more in-depth information on this groundbreaking design.
