QED Performance Audio 40: refined analogue interconnect for detailed listening

The QED Performance Audio 40 is an analogue interconnect designed for music lovers who want a clear, stable and well-timed signal path between hi-fi components. It sits within QED’s acclaimed Audio 40 series, a range created to reflect more than 40 years of experience in audio connectivity. This cable is a strong choice for linking a CD player, DAC, streamer, preamplifier or integrated amplifier fitted with RCA connections, especially in systems where detail, timing and tonal balance matter.

At the heart of the QED Performance Audio 40 are Complementary Conductor™ technology, 99.999% oxygen-free copper conductors, double shielding and Anamate™ RCA plugs. Together, these elements are intended to protect the analogue signal from unwanted interference while maintaining clarity and musical flow. The dedicated Ferrite insulation adds another layer of signal control, helping the cable perform beyond a basic interconnect without making unrealistic claims about changing the character of the entire system.

In everyday use, the Performance Audio 40 is well suited to stereo setups where a standard RCA cable may limit the quality of the connection between source and amplifier. It can be used between a DAC and preamp, a streamer and amplifier, or a traditional disc player and integrated amplifier. For best results, keep the cable away from tightly bundled power leads where possible and avoid sharp bends during installation. Choose the QED Performance Audio 40 for a considered, practical upgrade to your hi-fi chain.
