no.1 loudspeaker cables.   The conductor is made of very pure copper. The cable is built up of 1-mm2 conductors, which are built up by 126 0.1-mm2 wires. A 3-metre bi-wiring set consists of 60 metres of conductor. The conductors are wound around a core made of thin Teflon threads. The purest form of Teflon insulation without any colour additives is used on the outside. The tube containing the Bybee filter is made of PVC-free plastic, which also is crush-proof. The plaited outer coating is also PVC and halogen free. A tightly plaited copper shield lies between the outer coating and the conductors, which is not only for preventing noise and interference, but also as a stabiliser against micro phonics.   no.1 loudspeaker cables.
