I highly recommend the Totaldac D1 USB Cable/Filter. It can be had for less than your budget.

Besides myself, many other Audiophiles have found it to best other highly regarded USB cables at more then twice the price.
While I have not tried it some like the Audioquest Diamond. Though it is slightly more then your budget at times you can find a used one at/or below your budget.
Also check out this thread at CA. If you can wait around a month it may be worth the wait.
