As previously mentioned, the poles are reversed. say right is left and vice versa (but that one can simply turn) is the prisoner annoyed soppelt shielded cables solid and quite thick. The connectors are not as I had thought of plastic, but it seems to me aluminum, which has a positive effect on the stability. the spurious signals are minimal. speak to other compared cheap cables virtually absent. To hear the sound I had my amp already turn up to half, the old cables were heard already at 9 clock position. I would recommend this cable definitely because of the price and quality of basic votes. the cables are incidentally not break as easily as the twice as expensive cable InLine. ;)
