Yes, our cables are directional and very audibly so. The directionality of the cables in the desired way, i.e. to have an easily perceptible effect on the reproduction, is achieved thanks to our IST technology. Even a less experienced listener should be able to immediately identify the right/wrong direction of our cables in a listening test. Any of the cables with the same termination on both sides can be used for this test, e.g. RCA interconnect cables, Ethernet cable or speaker cables. It is therefore important to plug our cables with the same terminations on both sides in the correct direction. The directionality of the cable is indicated by an arrow on the movable metal tube with the logo and series name. As far as cable directionality in general is concerned, this is a complex issue to which we have devoted a long period of our research and we have also reached new insights in this respect, which we have capitalized on in the development of IST technology for materials processing and subsequently in product development and production.
