PP (personal preference) is important, and thanks for saying the amp and speakers (you'd be surprised how many people don't!) All three are excellent products. I use one of them ;--)
But the most important factor in A--B'ing ANY kind of cables is making sure your samples are BROKEN IN! Which is why I agree with Mcondon's recommendation that you put up some non-refundable deposit money to get your samples from the Cable Company. And although it's unlikely they'll send you a pair of new ones, don't be afraid to specify that you want all USED cables! Otherwise you could be making an expensive mistake. My $ 0.02 ;--)
