A few years ago I aquired some speaker cable from a friend, who is the manager of a Practical Hi-Fi store. She said the cable was worth £5/m so I was pretty chuffed when she cut me five metres. The thing is, it has KEF written all over the sleeving, but I can't find any information about it on the net. It has bright green sleeving, and is pretty chunky. Did KEF make only one model of speaker cable, or does anyone know where I can find information about the cables they produced? I just want to know if it's decent stuff, or whether I should upgrade. Thanks.
