# QED Reference Audio 40 RCA Cable

The QED Reference Audio 40 is a premium analogue interconnect cable designed to deliver highly accurate signal transfer between hi-fi components such as CD players, DACs, streamers and amplifiers.

Using silver-plated 99.999% oxygen-free copper conductors and a low-loss LDPE dielectric, the cable maintains excellent conductivity while minimising signal loss, helping preserve the detail, timing and dynamics of your music.

Its advanced asymmetrical twisted pair geometry and full electromagnetic shielding help protect the audio signal from external interference, ensuring clean and consistent performance.

A Zn/Mn ferrite-impregnated jacket absorbs high-frequency noise, while gold-plated QED Analoc2™ RCA connectors provide a secure, low-eddy-current connection, making the Reference Audio 40 an excellent upgrade for high-quality stereo systems.
