For years now, connecting cables are counted as components. Differences in sound have two reasons: on the one hand the quality of transmitting the signals is important, on the other hand, there is the question of what happens with disturbances from the outside. In addition, the conductor material has some influence on the overall sound. Experience shows that there is no unique, perfect solution. Graditech is going a new way with the Lumi 3. With the help of bridges which are mounted into a finely crafted wooden block, a transmission mixture of different copper kinds can be chosen. The result is a perfect sound solution independent from the respective system. This also means that the Lumi 3 can also be used when other components are changed. The sound quality is more than outstanding.
