Best Sounding USB Cables?

@mastering92

Within a cable there is no such thing as a "digital signal."  There is only an analog signal attempting to be a sequence of perfect square waves. So everything matters. 

Like so many others here, I have heard considerable differences among USB cables though I do not use the the power line at all. 

I have found that solid core cable is best for USB. As for solid core copper, or silver plated solid copper or solid silver, these are different flavors. Which tastes best will depend upon what electronics is at either end.

You don't have to spend enormous amounts of cash as very good solid core cables can be found at very reasonable prices.
