The Dynavox Black Line series is the highest expansion stage in all Dynavox cable series. The Black Line is characterized mainly by the use of the best materials and a sophisticated cable structure coupled with the usual high quality workmanship. The maxim in the development was: Unadulterated sound at affordable prices. The Black Line stereo cinch cable does exactly that and of course has a 99.9999% OFC conductor which has been packed into a complex shield: first there is an outer PVC mesh for mechanical protection. These include 2 levels of aluminum foil, 2 levels of soft polyethylene and 2 levels of copper screen (99.9999% OFC) for further mechanical and electrical shielding. High-quality RCA plugs with gold-plated contacts and a direction indicator complete the features. Packaging in high quality hard cardboard box with window. Outer diameter 11.8 mm.
