# QED Signature Audio 40 RCA Cable

The QED Signature Audio 40 Cable is a high-end analogue interconnect designed to deliver exceptional clarity and detail 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 Teflon™ dielectric, the cable is engineered to maintain accurate signal transmission while reducing distortion and preserving the full dynamics of your music.

Its advanced construction includes asymmetrical twisted pair geometry and comprehensive electromagnetic shielding to protect the signal from interference.

Rhodium-plated QED Analoc2™ RCA connectors provide a secure, low-eddy-current connection for improved timing and detail, while cryogenic treatment and a ferrite-impregnated jacket help reduce unwanted noise, making the Signature Audio 40 an excellent choice for high-performance stereo systems.
