Hi,
we've had many on here ask if they can extend speaker wires and the usual answer is yes you can, however your the first ( i believe ) to actually ask if you can upgrade the cables!, well thats down to personal preference and what you need to remember here is i believe the existing cables are only plug in's on one end, i believe the cables are actually fixed to the speakers, This is already a well rated piece of kit so im not sure if its worth the effort taking the speakers apart to solder new cable in place, plus if your still in warranty for the product then that will go out the window also.
its up to you of coarse, personally i wouldent do it.
