This cable is part of the Shawline cable range which includes loudspeaker cable and digital and analogue interconnects. Shawline cables have been designed to perform together. However, all Chord interconnects and speaker cables follow a similar design philosophy. This means that all Chord cable ranges are compatible with each other.

Epic XL combines elements of Chord's Epic and Signature Reference/XL speaker cables. A specially chosen soft PVC internal jacket is added to correctly space the shielding and minimise mechanical noise. A high density braid and foil shield is applied to each set of conductors and this is in turn protected by a translucent outer jacket, again chosen to reduce unwanted mechanical noise.
