The new Havana audio cable uses a twisted 4 x conductor configuration with a High density polyethylene dielectric (or the bit that surrounds the conductors). Surrounding this is a high density OFC braid and then the Havana trademark loose wrap mylar foil shield. This is covered by a translucent black PVC jacket which gives the cable its 'cigar' like appearance.
The cable produces great detail from almost all audio sources and needs properly burning in before optimum sound is achieved. It sounds great from new but will get better over weeks of use!
