I need some 'wife friendly' speaker cable for my rear speakers in my 5.1 set up. It needs to be as discreet as possible as it has to be trailed along the top of the skirting boards. My speakers are KEF Eggs (Version 1) and i'm running them through a Yamaha HTR5540 AV receiver. My fronts are connected with standard QED speaker cable, but the wife says this is too bulky. Anyone any thoughts on a good quality cable (up to £2.50/m) that I could use.
