I have a Panasonic Dolby Digital receiver in conjunction with a Elac Cinema XL Set III, including SUB 111.2 ESP. Price four years before 1500, -, receiver well 200, -. Connected are the small speaker on the receiver, even though the subwoofer also has connections. The sub was until about two months associated with a normal, thin audio cinch cable, of course, came through the many cable faults in the form of hum on. Then I had briefly used a digital coaxial cable and the disturbances were weg.Da I needed this 10m cable for my other apartment on the PC and also had bought it had another her.Nach looking long, I chose the Oehlbach Subwoofer Cable. When I was back at home on the weekend, I took out the cable, which was immediately struck me that it is as smooth as silk. Super, so it can be better laid. Then angeschmissen the system and first turned very quiet ... nothing ... no hum. Then I had NEN iPod connected and made a little louder, funtioniert. I mean before it had even works but if I / we had turned a little quieter bugged me the hum. Is normal if a cable is not shielded properly. But I found very positive that the cable is so soft, other cables in strength are sometimes quite rigid.
