QED Reference Audio 40 Interconnects

QED's Reference series is the penultimate range of interconnects in their extensive catalogue. Featuring an entirely new design concept, the cordage of the Reference models are designed first and foremost for low capacitance. This is because QED has identified this factor as being a significant player in the high fidelity listening experience, by retaining a low capacitance, sound signals are better looked after and allow for a more collected and detailed hifi performance. 

The Reference range also utilises QED's 'Complementary Conductor Technology' to ensure a high-frequency detail, and their Analoc Technology to optimise signal integrity. All QED interconnects and cables feature a lifetime warranty, including the Reference series.

QED Reference 40 Stereo Phono to Phono interconnect is the choice for those who are looking to expand their component’s sound quality within their Hi-Fi or Home Cinema set-ups.

The features that the Reference interconnects has are unmatched in its league for the value of money. The Reference range of audio interconnects has been designed for those who seek refinement in the connection between system components, without the price that often puts off many people from their ideal choice of interconnections. Heavily featured in the QED Reference Phono interconnects is the use of 99.999% Oxygen Free Copper conductors, symmetrical geometry pairs, double screened, Mylar foil wrap and an oxygen-free braiding.

Of course, Reference doesn’t just stop there. Eight leaf 24K gold RCA connectors and ground ring for connection durability, also features precision-engineered plugs, with grips, to finish off this high-performance audio interconnect from QED.
