I'm not familiar with Quicksilver speaker cable, but when I checked their website, they say that the cable is 15 guage, however, there is no comment as to how many cables make up the final product. on the flipside...I checked out the Homegrownaudio website and noticed that they use 32 strands of 22 guage sliver wire in their cables but they do not say what the final cable guage is. I'm not sure of how guages add up...but could it be that you might need to have more cables. just a guess on my part. hope it helps.
