Product Description


Signature Audio 40 is an entirely new design concept from QED laboratories.

The cordage is designed primarily for low capacitance as this has been identifed 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 QED's Complementary Conductor TechnologyTM for high frequency detail and our AnalocTM Technology to maximise signal integrity and the result is what we feel to be the most innovative interconnect ever made by QED.
