I'm getting a new Onkyo 876 soon with some new speakers to give me a 7.1 system Comes with a length of QED Micro Speaker Cable which should do most of the speakers. I also have some QED 79 Strand speaker cable in the garage which I was going to use on 2 of the surround speakers. I'm loath to splash out on more cable as I have quite long cable runs to do. Does anyone think I will be able to notice a difference in sound from the 2 surrounds wired up with the different cable?
