I have 2 era 100s in two rooms. One is in the kitchen and is great. Sometimes I like to bring the second one in to make a stereo pair which sounds much better. However this is difficult as the mains wire is looped through furniture so I would like a second mains wire. No other wires fit the era 100 (I have a five, sub and beam) and I can't find one for sale. 

Any suggestions on how to get a mains wire or do I need to look at a cheap Chinese one? Surely someone else has had this issue or has damaged a cable and needs a replacement.
