When replacing my AV Receiver I replaced my speaker cables. I chose here to the pure copper wire. Compared to the old (cheap) cable drops here primarily to the higher weight, but the cables also affects overall quality. Whether it is also reflected in a better acoustics of the system, it is difficult to assess and often a subjective impression. In any case, these product value in order and the delivery was carried out very quickly. Caution: The cable does not come into the mapped role, so a star deduction.
