Have the cable purchased directly from the devil and not from Amazon and can not understand the negative review because of the hum. Got my two Harman / Kardon subwoofer clamped Perfect no hum. Just from a relaxed grip of the cable I did not notice it budge !!! I do not know what has been connected for an old receiver with ausgelutschten connections to it. With me everything is top with tightness of the cable and no hum. Well worth buying. Immediately strike as it now no longer is the cable in hell in the shop to buy.
